Answer 2

Explicação passo a passo:

Para achar as equivalentes multiplica e/ou/divide os numeradores e denominadores pelo mesmo valor

a. 3/8

b. 2/5

c. 7/9

d. 9/10​

a

3/8 * 2/2 = 6/16 >>>>

3/8 * 3/3 = 9/24 >>>>

3/8 * 4/4 = 12/32 >>>>>

3/8 * 5/5 = 15/40 >>>>

3/8 * 6/6 = 18/48 >>>>>

b

2/5

2/5 * 2/2 = 4/10

2/5 * 3/3 = 6/15

2/5 * 4/4 =8/20

2/5 * 5/5 = 10/25

2/5 * 6/6 = 12/30

c

7/9

7/9 * 7/7 = 49/63

7/9 * 8/8 = 56/72

7/9 * 9/9 = 63/81

7/9 * 2/2 = 14/18

7/9 *3/3 = 21/27

d

9/10 =

9/10 * 2/2 =18/20

9/10 * 3/3 = 27/30

9/10 * 4/4 = 36/40

9/10 * 5/5 = 45/50

9/10 *6/6 = 54/60
