Part 1: HESI A2 Math Practice Test
Basic Number Concepts and Definitions
Question 1: What is a whole number?

decimals (0, 1, 2, 3, 4, 189, 293)
Question 2: What are integers?

Example: -1, -2, -3, -4, -5, 0, 1, 2, 3, 4, 5
,Question 3: What is a prime number?
Correct Answer: A number that is only evenly divisible by 1 and itself,
with no remainder or decimal
Question 4: What is a composite number?
Correct Answer: A positive integer (whole number) formed by
multiplying two smaller integers together; all divisible by 2; can be
evenly divided by numbers other than 1 or itself
Question 5: What are real numbers?
Correct Answer: Rational and irrational numbers
Question 6: What are rational numbers?
Correct Answer: Any number that can be expressed as a fraction with
a non-zero denominator
Fractions
Question 7: What is a proper fraction?
Correct Answer: The numerator is less than the denominator
Question 8: What is an improper fraction?
Correct Answer: The numerator is larger than the denominator
,Question 9: What are mixed numbers?
Correct Answer: Combine a whole number with a proper fraction
Question 10: How do you reduce or simplify fractions?
Correct Answer: Divide the numerator and denominator by low
numbers (2, 3, or 5) until arriving at a simple fraction. Use the greatest
common factor
Decimals
Question 11: What are decimals?
Correct Answer: What follows a decimal is a value less than 1 and
added to the integer number preceding the decimal; represents
division between the whole portion and the fraction (or decimal)
portion of a number. Example: 3.15 (3 = whole; .15 = decimal/fraction)
Question 12: What happens when multiplying by 10?
Correct Answer: Move the decimal 1 position to the right, making a
larger number than before
Question 13: How do you add and subtract decimals?
Correct Answer: Line up the decimals
Question 14: How do you multiply decimals?
Correct Answer: Pretend decimals are not there, then count how many
, decimals are in the original problem; use the total to place the decimal
in the same number of spaces over
Ratios, Rates, and Proportions
Question 15: What are ratios?
Correct Answer: Used to show the relationship between two quantities
Question 16: What are rates?
Correct Answer: Used to compare two quantities with different units
Question 17: What are unit rates?
Correct Answer: The denominator in the comparison of two units is 1
Question 18: What is a conversion factor?
Correct Answer: A ratio of equivalent measurements used to convert a
quantity from one unit to another
Question 19: What is a scale factor?
Correct Answer: The ratio between two similar geometric figures
Question 20: What are proportions?
Correct Answer: A ratio in fraction form set equal to another ratio in
fraction form
