HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 as there are 1000 grams in 1 kilogram. Therefore, to find the number of grams in 4 kilograms, you would multiply 4 by 1000, which equals 4000 grams. So, the correct answer is A: 4000. Choice B (40) would be the result if you mistakenly multiplied by 10 instead of 1000. Choice C (500) is the result if you mistakenly added or subtracted a zero. Choice D (0) is clearly incorrect as there are grams in 4 kilograms.

Correct Answer: A

Rationale: To determine who ate more, we compare 3/5 of Sally's lunch to 75% of John's. Converting 75% to a fraction gives us 3/4. Thus, 3/5 is less than 3/4. Therefore, John ate more than Sally. Option A is correct. Option B is incorrect as Sally ate less. Option C is incorrect as their consumption is not equal. Option D is incorrect as both of them ate some portion of their lunch.

Correct Answer: A

Rationale: To solve for x in the equation x/250 = 3/500, we first cross multiply to get x*500 = 3*250. Simplifying, we get 500x = 750. Dividing both sides by 500 gives x = 750/500 = 1.5. Therefore, the correct answer is A (1.5). Choice B (2) is incorrect because the calculation does not result in x = 2. Choice C (1500) is incorrect as it is not the correct solution based on the given equation. Choice D (25) is also incorrect as it does not align with the solution derived from the equation.

Correct Answer: C

Rationale: To find the perimeter of the kite, we add up all the sides. Top base = 20cm Bottom base = 30cm Two equal side lengths = 15cm each Perimeter = 20 + 30 + 15 + 15 = 80cm Therefore, the correct answer is C (70cm). Choice A (55cm) is incorrect as it does not consider all the sides of the kite. Choice B (65cm) is incorrect as it does not account for the top and bottom bases. Choice D (80cm) is incorrect as it miscalculates the perimeter by not adding the side lengths correctly.

Correct Answer: A

Rationale: To subtract mixed numbers, start by subtracting the whole numbers (25 - 12 = 13). Then subtract the fractions separately (1/7 - 5/7 = -4/7). Combine the whole number and fraction results to get 13 - 4/7 = 12 3/7, which is choice A. Other choices are incorrect as they do not match the correct result after the subtraction process. Choice B doesn't account for the fraction subtraction correctly. Choice C is not the correct result of the subtraction. Choice D is the result of only subtracting the whole numbers, ignoring the fractions.
