Question

Write each number as a product of the gcf and another number. Then use the distributive property to rewrite the sum(36 and 45)

Answer 1

Answer: 9 × 4

9 × 5

9(4 + 5)

Explanation:

36 = 9 × 4

45 = 9 × 5

so, GCF is 9.

36 + 45 = 81

= 9(4 + 5)

= (9 × 4) + (9 × 5)

= 36 + 45

= 81

ALTERNATELY :

36 + 45 = 81

= 9(4 + 5)

= 9 × 9

= 81
