Question

Halla los términos desconocidos en cada una de las razones dadas:

1ra.6/5 = 12/10 = x/15 = 30/z

2da. 4/7 = 8/14 = 20/y = w/42

Answer 1

6/5 = 12/10 = x/15 = 30/z:

12/10 = x/15   x = 12 x 15/10 = 180/10= 18    18/15 = 30/z  Z= 15 x 30/18 = 450/18 =25

4/7 = 8/14 = 20/y = w/42:

8/14 = 20/y  Y= 14x20/8 = 280/8 = 35     20/35 = w/42 = W=20x42/35 = 840/35 = 24

Espero te ayude. :3
