Answer 1

Solución

A

6/15 = 2/x

2/5 = 2/x

2/5x = 2

2x/5 = 2

2x = 2 × 5

2x = 10

x = 10/2

x = 5                       6/15 = 2/5

B

14/18 = x/9

7/9 = x/9

7/9 × 9 = x

7 = x

x = 7                      14/18 =  7/9

C

x/7 = 12/28

x/7 = 3/7

x = 3/7 × 7

x = 3                     3/7 = 12/28
