Question

if a is directly proportional to b and when a= 4, b = 2 then if a = 8 then b=?​

Answer 1

here a= 4 then b = 2

a= 1 , b = 2/4

a= 8 then b= 2/4*8= 4

hope it helps

Answer 2

Step-by-step explanation:

When a = 4, b = 2

It means, a is 2 times of b

a = 2b

When a = 8, b = ?

a = 2b

8 = 2b

8 / 2 = b

4 = b
