Answer 2

Answer with Step-by-step explanation:

a. 5,600 ÷ 20

= 560 ÷ 2 (Cancelling the zeros of numerator and denominator)

=280

b. 475 ÷ 25

= (5×95) ÷ (5×5)

= 95 ÷ 5 (Cancelling 5 of numerator and denominator)

= 19

c. 650 ÷ 50

= 65 ÷ 5 (Cancelling the zeros of numerator and denominator)

= 13

d. 7,280 ÷ 80
