## Welcome to the free HESI Mathematics Practice Test.

The attached sample test contains 17 HESI mathematics questions, so you can understand precisely how to prepare for the digital part of the upcoming HESI test.

The Health Education System Corporation Conformation Assessment HESI mathematics practice test contains 50 scientific knowledge pieces and covers several subsections. These subsections are basic operations; decimals, fractions and percentages; proportions, ratios, ratios and military time; and algebra.

Each question is accompanied by a correct answer and a clear answer (very similar to using the inquiry bank in our HESI mathematics practice test package).

At the end of the training test, you will get a score report that separates the math subtopics that you should zero to improve quickly.

Correct! Wrong!

Explanation:

#### 1 liter contains how many milliliters?

Correct! Wrong!

Explnation:
The volume units' conversion factor of liters to milliliters is 1000.
1 liter = 1000 Milliliters
1 Milliliter = 0.001 Liters
This means that there are 1000 milliliters in one liter. Multiply the value in liters by the conversion factor to determine the number of milliliters in a liter.
One milliliter refers to 1000 of one liter. The volume of a cube whose sides are equal to 10 mm gives 10 x 10 x 10 = 1000 milliliters

#### Each pound has 453.59 grams. 6,577 grams is the weight of a baby. In pounds and ounces, how much does the baby weigh?

Correct! Wrong!

Explanation:
6577 grams/453.59 grams per pound = 14.5 pounds.
There are 16 oz. per pound, so .5 pounds = 8 oz.

#### The waist circumference of a man is 88.9 centimeters. What is his waist measurement in inches?

Correct! Wrong!

Explanation:
To convert centimeters to inches, divide by 2.54. 88.9/2.54 = 35 in.

#### In Celsius, what are 98.6 degrees Fahrenheit?

Correct! Wrong!

Explanation:
To convert Fahrenheit to Celsius, you subtract 32 degrees and multiply by 5/9.
So 98.6-32=66.6. 66.6*5/9 = 37 degrees Celsius

#### A meter is made up of how many centimeters?

Correct! Wrong!

Explanation:
The conversion factor of the metric length units’ meter (m) to centimeters (cm) is 100.
1 meters (m) = 100 centimeters (cm)
The conversion factor of the metric length units’ meter (m) to centimeters (cm) is 100.
If you want to find how many centimeters are in meters, you will simply multiply the value by 100.

#### In its simplest form, express 0.125 as a fraction.

Correct! Wrong!

Explanation:
0.125 = 125/1000 = 5/40 = 1/8

#### In its simplest form, express 35 percent as a fraction.

Correct! Wrong!

Explanation:
35% = 35/100 = 7/20

#### How do you represent 7/40 as a percentage?

Correct! Wrong!

Explanation:
7/40 = X/100
(7)(100) = (40)(x)
700 = 40x
x = 700/40
x = 70/40
x = 35/2
x = 17.5

Correct! Wrong!

Explanation:
20:30
20 − 12 = 8
8:30 PM

#### How many centimeters is 1 foot? (Note that one inch equals 2.54 cm.)

Correct! Wrong!

Explanation:
1 foot = 12 inch.
1 inch = 2.54 centimeters. <br. Therefore, 1 foot = 12 x 2.54 = 30.48 centimeters.

#### In a military hospital, a nurse's shift runs from 1400 to 2100. When does the nurse start and finish her shift?

Correct! Wrong!

Explanation:
Military time is based on a 24 hour clock. To convert from military time to standard time, simply
subtract 1200 from the time. 1400 - 1200 is 2 pm.

#### In grams, how would 350 milligrams be expressed?

Correct! Wrong!

Explanation:
350 mg = ? g Recall that 1 g = 1000 mg
1 g/1000 mg = x g/350 mg
(1)(350) = (1000)(x)
350 = 1000x
x = 350/1000
x = 0.350 g
Alternatively, you can simply move the decimal point of the 350 mg three spaces to the left.

#### Every 8 hours, the patient must take pain medication. When will they receive the third dose, if the first dose was given at 22:00 (military time)?

Correct! Wrong!

Explanation:
22:00 = 10:00 PM (first dose)
Second dose was given 8 hours after first dose:
10:00 PM + 8 hours = 6:00 AM
Third dose was given 8 hours after second dose:
6:00 AM + 8 hours = 2:00 PM

#### The active component in a pill is 0.45 mg. What fraction would this decimal be expressed as? Make sure you write it in the simplest form.

Correct! Wrong!

Explanation:
0.45 = 45/100 = 9/20

#### For the day, a patient on a clear diet consumes the following: 2 quarts water 1 clear soup serving (8 oz.) 1 cup of coffee (8 oz.) His drainage bag shows 1,000 mL for the previous day, according to a nurse who is checking his intake and output. What is his milliliter deficit?

Correct! Wrong!

Explanation:
The patients total intake is calculated first by converting everything to ounces:
2 pints of water x 16 oz per pint = 32 oz.; 32 oz. water + 8 oz. coffee + 8 oz. soup = 48 oz.
To convert ounces to milliliters (mL) multiply by 30 oz./milliliter. 48 oz. x 30 ox/mL = 1440 mL.
Therefore the deficit in milliliters is 1440-1000 = 440 mL

#### A car dealer sells ten different brands of automobiles. The dealer's typical daily sales are: Honda has two versions, each of which sells 20 units per day. Toyota has three models, each of which sells 15 units every day. Kia has only one model, but it sells seven per day. Ford has four models and sells six of each per day. How many automobiles are sold every day in total?

Correct! Wrong!

Explanation:
2 hondas x 20 cars = 40
3 toyotas x 15 cars = 45
1 kia x 7 cars = 7
4 fords x 6 cars=24
40+45+7+24 = 116 cars

#### Two-thirds of an ounce of liquid is contained in a sample. What is the volume in milliliters (mL)?

Correct! Wrong!

Explanation:
To convert oz. to mL, multiply by 30 oz/mL.
2/3 x 30 = 60/3 = 20 mL

#### 25 chainsaws, 14 snow blowers, 18-floor sanders, 12 leaf blowers, and 19 power washers are among the inventory of a tool rental company. How many tools can be rented if 25% of the total inventory is available for rental?

Correct! Wrong!

Explanation:
The total inventory is 88 (25+14+18+12+19).
25% of 88 = 88 x .25 = 22

#### What is the length of a kilometer in meters?

Correct! Wrong!

Explanation:
1 kilometer = 1000 meters Therefore, there are 1000 meters in one kilometer.
If you want to determine the number of meters in a kilometer, simply multiply the value in kilometer by the conversion factor.

#### A doctor advises a patient to reduce their intake of diet soda by 25%... The patient currently consumes four 12 oz. diet Coke cans per day. If the patient cuts his soda intake by 25%, how many ounces of diet soda may he drink?

Correct! Wrong!

Explanation:
Patient currently consumes 48 ounces (4x12 oz).
Patient has to give up 25% of 48 ounces = 48 x .25 = 12 oz. <br. Therefore, the patient can drink 48 - 12 = 36 ounces.

#### In a kilogram, how many grams are there?

Correct! Wrong!

Explanation:
1 kilogram = 1000 grams Formula:
multiply the value in kilograms by the conversion factor '1000'.
So, 1 kilogram = 1 × 1000 = 1000 grams.

#### A hospital gives birth to 1,820 infants per year. How many females were born in a year if 55 percent of the babies born were boys?

Correct! Wrong!

Explanation:
If 55% are boys, then 45% must be girls.
1820 x 45% = 819

#### How many pounds are 10 kilograms?

Correct! Wrong!

Explanation:
The correct answer is 22 pounds

#### According to the instructions, you must dilute a powder in 3 quarts of water. You only have a container with a liter marking on it. To dilute the powder, how many liters would you use?

Correct! Wrong!

Explanation:
1 quart = 32 oz. Therefore 3 quarts = 96 oz.
There are 30 milliliters per oz, so 96 oz = 2,880 milliliters.
There are 1000 milliliters per liter, so 2,880 mL = 2.88 liters
