HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
What is the result of adding 7/8 + 9/10 + 6/5?
Correct Answer: A
Rationale: To add fractions with different denominators, first find a common denominator. In this case, the least common multiple of 8, 10, and 5 is 40. Then, convert each fraction to have a denominator of 40: 7/8 = 35/40, 9/10 = 36/40, and 6/5 = 24/40. Add them up to get 95/40 which simplifies to 2 & 15/40 = 3 & 3/8 = 3 & 39/40 (Choice A). Other choices are incorrect because they do not represent the correct sum of the fractions.
Question 2 of 5
How many ounces are in 2.5 gallons?
Correct Answer: C
Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.
Question 3 of 5
Subtract 12 1/8 - 9 1/2.
Correct Answer: A
Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.
Question 4 of 5
How many pounds are in 144 ounces?
Correct Answer: D
Rationale: To convert ounces to pounds, we know that 1 pound is equal to 16 ounces. Therefore, to find how many pounds are in 144 ounces, we divide 144 by 16, which equals 9 pounds. The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds. C: 8 pounds - Incorrect, as 144 ounces do not equate to 8 pounds.
Question 5 of 5
A newborn weighs 3,459 grams. There are 453.59 grams per pound. What is the infant's weight in pounds and ounces?
Correct Answer: A
Rationale: To convert the infant's weight from grams to pounds, divide 3,459 by 453.59 to get approximately 7.63 pounds. Since 1 pound is equal to 16 ounces, multiply the decimal part (.63) by 16 to get 10.08 ounces. Therefore, the infant's weight is 7 pounds and 10 ounces, making choice A the correct answer. Choices B, C, and D are incorrect due to incorrect conversions or calculations. B and C have the pound and ounce values switched, and D incorrectly converts the weight to 3 pounds and 13 ounces.
