1) Divide by common factors.

2) Divide by using GCF.

Divide by common factors • Divide by common factors until the common factor is 1. • You can start dividing by 2 since both the numbers are even. 20 ÷ 2 10 ---------- = ----- 24 ÷ 2 12 But both 10 and 12 are also even so they are divisible by 2. 10 ÷ 2 5 ---------- = ----- 12 ÷ 2 6 • Since 5 and 6 do not have any common factor so 5/6 is the simplest form of 20/24. |
Divide by using GCF• First find the GCF of 20 and 24. 20 : 1, 2, 4, 5, 10, 20 24 : 1, 2, 3, 4, 6, 8, 12, 24 • The common factors of 20 and 24 are 2 and 4. The GCF of 20 and 24 is 4. • Divide both the numerator and denominator by 4. 20 ÷ 4 5 ---------- = ----- 24 ÷ 4 6 |
