HESI A2 Math
Question 1 of 10
What is the value of 3 + 4 × 5 when the order of operations is followed?
Not quite. The answer is B
Key takeaway
Multiplication comes before addition, so 4 × 5 = 20 and 3 + 20 = 23. The answer 35 comes from wrongly adding first.
What is 4 2/5 + 3 5/6 as a mixed number in lowest terms?
Not quite. The answer is B
Key takeaway
Convert to 22/5 and 23/6, then use LCD 30: 132/30 + 115/30 = 247/30. Dividing gives 8 with remainder 7, so 8 7/30.
In the number 3.047, which digit is in the hundredths place?
Not quite. The answer is A
Key takeaway
3.047 is 3 ones, 0 tenths, 4 hundredths and 7 thousandths, so 4 is in the hundredths place.
How is 2/3 correctly written as a decimal and a percent?
Not quite. The answer is C
Key takeaway
2 ÷ 3 gives 0.666..., a repeating decimal, which is 66.6 repeating %. The 0.333... option is 1/3.
Solve the proportion 7 : 42 :: 4 : x. What is the value of x?
Not quite. The answer is D
Key takeaway
Write 7/42 = 4/x. Cross-multiplying gives 7x = 168, so x = 24.
A client who is 5 ft 9 in tall is converted to centimetres. What is the height to the nearest whole number?
Not quite. The answer is B
Key takeaway
5 ft 9 in is 60 + 9 = 69 in, and 69 × 2.54 = 175.26 cm, or about 175 cm.
How is 12:30 AM written in military time?
Not quite. The answer is A
Key takeaway
At 12 AM the hour becomes 00, so 12:30 AM is 0030. 1230 would be 12:30 PM, just after noon.
A 154 lb patient is ordered 5 mg/kg, using 2.2 lb per kg. With 250 mg tablets, how many tablets are needed?
Not quite. The answer is A
Key takeaway
154 ÷ 2.2 = 70 kg, and 70 x 5 = 350 mg. Then 350 / 250 = 1.4 tablets.
Which operation correctly undoes division in an equation such as x ÷ 5 = 8?
Not quite. The answer is D
Key takeaway
Multiplication is the inverse of division, so multiply both sides by 5 to get x = 40. Addition and subtraction undo each other, not division.
Hand-hygiene compliance rose from 70% in January to 82% in May. What is the percent change?
Not quite. The answer is C
Key takeaway
Percent change = (new − old) ÷ old × 100 = (82 − 70) ÷ 70 × 100 ≈ 17.1%. Using 82 as the denominator gives 14.6%, and 12 is only the difference in percentage points.

Tips
How to score higher on math
- Estimate before you calculate. A misplaced decimal point is the error that turns 1.4 tablets into 14.
- Learn the household to metric conversions cold: 1 tsp = 5 mL, 1 tbsp = 15 mL, 1 fl oz = 30 mL, 1 kg = 2.2 lb.
- Set up every proportion with the same unit on top on both sides, then cross-multiply.
- Round only the final answer, and only to the places the question asks for.
