HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.

Correct Answer: D

Rationale: To calculate the total days off, add Bill's remaining vacation days (2.5) and sick days (1.25): 2.5 + 1.25 = 3.75 days. Since Bill is using all his sick days and vacation days, he will have 3 full days off work. Therefore, the correct answer is D (4 days). Choices A, B, and C are incorrect as they do not consider the combination of remaining days and assume a different outcome.

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: A

Rationale: To find the correct answer, we need to set up a proportion: 4 cups of sugar for 120 cookies is equivalent to x cups of sugar for 90 cookies. Cross multiply to get 4*90 = 120*x, which simplifies to 360 = 120x. Divide by 120 to get x = 3 cups. Therefore, the correct answer is A: 3 cups of sugar. The other choices are incorrect because they do not align with the proportional relationship between the amount of sugar and the number of cookies in the recipe. Choice B, 2 cups, is too few as it would be for fewer than 90 cookies. Choice C, 1.5 cups, is even less than 2 cups and doesn't fit the ratio. Choice D, 4 cups, is the amount needed for 120 cookies, not 90.

Correct Answer: D

Rationale: To solve the proportion 1.2:x=14:42, we first find the ratio of the first pair (1.2:14) by dividing 1.2 by 14 to get 0.0857. Then, we find the ratio of the second pair (x:42) by dividing x by 42, which equals 0.0857. Therefore, x = 42 * 0.0857 = 3. Hence, the correct answer is D. Choice A is incorrect as 1.2 is not equal to 2. Choice B is incorrect as the ratio cannot be 0. Choice C is incorrect as the ratio is not 1.
