TSI Math Practice Test 2

Question 1

2.45 + 0.54 + 0.07 =

Accepted Answer

3.06

Answer

To add decimals, align the numbers vertically by their decimal points. Then, add the digits in each column, starting from the rightmost digit, and carry over to the next column as needed. Performing this operation for 2.45 + 0.54 + 0.07 yields a sum of 3.06.

Question 2

Which of the following represents the smallest value?

Accepted Answer

0.000799

Answer

To determine the smallest value among decimals, compare the digits from left to right, starting with the largest place value. The number 0.000799 has zeros in the tenths, hundredths, and thousandths places, indicating it is significantly smaller than the other options which have non-zero digits in higher place values.

Question 3

5.36 - 0.78 =

Accepted Answer

4.58

Answer

To subtract decimals, align the numbers vertically by their decimal points. Subtract the digits in each column, starting from the rightmost digit, borrowing from the left if a digit in the top number is smaller than the corresponding digit in the bottom number. Performing this calculation for 5.36 - 0.78 results in 4.58.

Question 4

Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased her production by 18%, how many dolls would Janet produce each month?

Accepted Answer

27

Answer

To find the new production, first calculate 18% of 23 dolls: 0.18 * 23 = 4.14 dolls. Since you cannot produce a fraction of a doll, round this to the nearest whole number, which is 4 dolls. Adding this increase to the original production gives 23 + 4 = 27 dolls per month.

Question 5

Two cars are side by side. One is 3.9 meters long. The other is 6% shorter. How long is the second car?

Accepted Answer

3.7 meters

Answer

First, calculate 6% of the first car's length: 0.06 * 3.9 meters = 0.234 meters. Then, subtract this amount from the first car's length to find the length of the second car: 3.9 - 0.234 = 3.666 meters. Rounding to one decimal place, the second car is approximately 3.7 meters long.
