Question

Answer the following
4/7x21=
5/8x40=
11/4x8=
2/5x60=

Answer 1

1. 4/7*21/1 = 84/7 = 12
2. 5/8*40/1 = 200/8 = 25
3. 11/4*8/1 = 88/4 = 22
4. 2/5*60/1 = 120/5 = 40

1st step: Rewrite your whole number over 1 so it’s also a fraction and easier to multiply

2nd step: multiply across (numerator*numerator and denominator*denominator)

3rd. Divide numerator (top number) by the denominator (bottom number)

This third step is also called simplifying

Answer 2

1. 4/7 x 21 = 12

2. 5/8 x 40 = 25

3. 11/4 x 8 = 22

4. 2/5 x 60 = 24

Explanation:

1. 4/7 x 21

= 4 * 21 / 7

= 84 / 7

= 12

2. 5/8 x 40

= 5 * 40 / 8

= 200 / 8

= 25

3. 11/4 x 8

= 11 * 8 / 4

= 88 / 4

= 22

4. 2/5 x 60

= 2 * 60 / 5

= 120 / 5

= 24
