Question

If 1/ 4 = a/12, then a = ?
If5/a = 20/28 , then a = ?
If a/3 = 4/6, then a = ?​

Answer 1

Step-by-step explanation:

1)

1/4= a/12

so, a= 3

2)

5/a = 20/28

so, a= 7

3)

a/3= 4/6

so, a= 2

Answer 2

Answer:

if 1/4 = a/12 then a = 12/4 = 3

if 5/a = 20/28  then a = (5x28)/20 , a = 7

If a/3 = 4/6, then a =( 4x3)/6 , a= 2
