UNIT ONE: MATH REVIEW




CHAPTER 1: FRACTIONS


QUESTION 1.1

Reduce the following fraction to lowest terms.
54/81 = _____

A) 2/3
B) 3/4
C) 6/9
D) 4/5

Answer: A) 2/3

, Rationale: To reduce 54/81, divide both numerator and denominator by their greatest common
divisor (GCD), which is 27. 54 ÷ 27 = 2, and 81 ÷ 27 = 3. So, 54/81 = 2/3. While 6/9 is
equivalent, it is not in lowest terms .

QUESTION 1.2

Reduce the following fraction to lowest terms.
105/135 = _____

A) 3/5
B) 5/7
C) 7/9
D) 9/11

Answer: C) 7/9

Rationale: The GCD of 105 and 135 is 15. Divide both by 15: 105 ÷ 15 = 7, and 135 ÷ 15 = 9.
So, 105/135 = 7/9 .

QUESTION 1.3

Reduce the following fraction to lowest terms.
39/65 = _____

A) 3/5
B) 5/7
C) 7/13
D) 13/15

Answer: A) 3/5

Rationale: The GCD of 39 and 65 is 13. 39 ÷ 13 = 3, and 65 ÷ 13 = 5. So, 39/65 = 3/5 .

QUESTION 1.4

Change the following improper fraction to a whole or mixed number.
325/16 = _____

A) 20 5/16
B) 19 3/16
C) 21 4/16
