HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.

Correct Answer: A

Rationale: To change 0.004 to a ratio, we need to express it as a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct because it accurately represents the ratio of 0.004. Choices B, C, and D are incorrect because they do not accurately reflect the equivalent ratio for 0.004.

Correct Answer: A

Rationale: To convert pints to milliliters, we need to know that 1 pint = 473.176 milliliters. Therefore, 5 pints would be 5 x 473.176 = 2365.88 milliliters. Rounding up, we get approximately 2400 milliliters. This is why choice A (2400 milliliters) is correct. Choices B, C, and D are incorrect because they do not accurately convert pints to milliliters based on the conversion factor provided.

Correct Answer: A

Rationale: To divide mixed numbers, convert them to improper fractions. 4 7/8 = (8*4 + 7)/8 = 39/8 and 1 1/6 = (6*1 + 1)/6 = 7/6. Then divide 39/8 by 7/6: (39/8) ÷ (7/6) = (39/8) * (6/7) = 234/56 = 4 5/28 (Choice A). The other choices are incorrect because they do not yield the correct result when following the correct steps for dividing mixed numbers.

Correct Answer: A

Rationale: To add fractions, we need a common denominator, which for 3, 6, and 5 is 30. So, we rewrite the fractions with a denominator of 30: 20/30 + 5/30 + 12/30 = 37/30. Simplifying 37/30 as 1 & 7/30 gives us the correct answer, choice A. The other choices are incorrect because they do not reflect the accurate sum of the fractions. Choice B is incorrect as it simplifies to 1 & 1/15, not 1 & 7/30. Choice C simplifies to 2/5, which is not the sum of the given fractions. Choice D simplifies to 3/4, which is also not the sum of the fractions provided.
