TEAS Math 4

Question 1

Convert 3.6 × 10⁻² to standard decimal notation.

Accepted Answer

0.036

Answer

A negative exponent of −2 moves the decimal 2 places left: 3.6 → 0.036.

Question 2

A patient weighs 176 lbs. A medication dose is 5 mg per kilogram of body weight. How many mg should be administered? (1 kg = 2.2 lbs)

Accepted Answer

400 mg

Answer

176 ÷ 2.2 = 80 kg; 80 × 5 = 400 mg.

Question 3

Solve for x: 4x/3 = 20

Accepted Answer

x = 15

Answer

Multiply both sides by 3: 4x = 60; divide by 4: x = 15.

Question 4

A store marks up items by 35% over cost. If an item costs the store $60, what is the selling price?

Accepted Answer

$81

Answer

Markup = 35% × $60 = $21; selling price = $60 + $21 = $81.

Question 5

Which of the following is the largest value?

Accepted Answer

9.8%

Answer

9.8% = 0.098, and 9/100 = 0.09 and 0.0989 < 0.098, so 9.8% ties for largest — but 9/100=0.09 < 0.098, making 9.8% = 0.098 the largest.
