Question

if a is directly proportional to b and when a= 8, b = 16 then if a = 16 then b=?​

Answer 1

Answer:

b = 32

Step-by-step explanation:

If a directly proportional to b and a when a = 8 ,

b = 16

Therefore , b = 2a

Then if a = 16

Therefore , b = 2a

=> b = 2 × 16

=> b = 32

Answer 2

a/b = constant

so

8/16= 16/b

=>b = 32
