These are original practice items written to the HESI A2 blueprint (4 options, no penalty for wrong answers), not actual exam questions. Try each one before you open the answer.
Mathematics: fractions and decimals sits inside the Mathematics section of the HESI A2. Our bank holds 33 verified items tagged to it, and the 4 below are a fixed sample so the page stays the same every time you open it. Each one shows the reasoning, not just the letter.
The topic tag comes from our own items rather than from a published syllabus, so treat it as a map of what we cover. For the official section breakdown see the HESI A2 page.
Question 1
What is the decimal equivalent of the fraction 3/4?
Correct answer: A
Divide 3 by 4: 3 ÷ 4 = 0.75.
Why the other options are wrong:
B: 0.50 is equivalent to 1/2.
C: 0.25 is equivalent to 1/4.
D: 1.33 is approximately 4/3, not 3/4.
Question 2
A nurse needs to administer 3/4 of a tablet. What is this amount expressed as a decimal?
Correct answer: C
3/4 = 0.75. To convert a fraction to a decimal, divide the numerator by the denominator: 3 ÷ 4 = 0.75.

A: 1.0 is the decimal equivalent of 1, not 3/4.
B: 0.5 is the decimal equivalent of 1/2, not 3/4.
D: 0.25 is the decimal equivalent of 1/4, not 3/4.
Question 3
A patient's lab result shows a value of 0.75 mg/dL. What is this value expressed as a fraction in simplest form?
Correct answer: C
0.75 is equivalent to 75/100, which simplifies to 3/4 by dividing numerator and denominator by 25.
Why the other options are wrong:
A: 7/10 equals 0.7, not 0.75.
B: 3/5 equals 0.6, not 0.75.
D: 1/2 equals 0.5, not 0.75.
Question 4
Convert the fraction 3/8 to a decimal.
Correct answer: D
3 ÷ 8 = 0.375. This is the exact decimal representation.
Why the other options are wrong:
A: 0.425 is the decimal for 17/40 or 34/80, not 3/8.
B: 0.3 is the decimal for 3/10, not 3/8.
C: 0.38 is a rounded approximation, but the exact decimal is 0.375.
