Answer:

1. 1/6

2. 1/15

3. 1/3

4. 1/3

5. 1/4

Step-by-step explanation:

Explanation of 1. Find the GCD (or HCF) of numerator and denominator

GCD of 8 and 48 is 8

Divide both the numerator and denominator by the GCD

8 ÷ 8 = 1

48 ÷ 8 = 6

Therefore, 8/48 simplified to lowest terms is 1/6.

Explanation of 2. Find the GCD (or HCF) of numerator and denominator

GCD of 3 and 45 is 3

Divide both the numerator and denominator by the GCD

3 ÷ 3 = 1

45 ÷ 3 = 15

Therefore, 3/45 simplified to lowest terms is 1/15.

Explanation of 3. Find the GCD (or HCF) of numerator and denominator

GCD of 13 and 39 is 13

Divide both the numerator and denominator by the GCD

13 ÷ 13 = 1

39 ÷ 13 = 3

Therefore, 13/39 simplified to lowest terms is 1/3.

Explanation of 4. Find the GCD (or HCF) of numerator and denominator

GCD of 9 and 27 is 9

Divide both the numerator and denominator by the GCD

9 ÷ 9 = 1

27 ÷ 9 = 3

Therefore, 9/27 simplified to lowest terms is 1/3.

Explanation of 5. Find the GCD (or HCF) of numerator and denominator

GCD of 3 and 12 is 3

Divide both the numerator and denominator by the GCD

3 ÷ 3 = 1

12 ÷ 3 = 4

Therefore, 3/12 simplified to lowest terms is 1/4.
