Question

A:B =4:5 if A=16 then the value of B is what?/

Answer 1

Step-by-step explanation:

A:B =4:5

A=4x

B=5x

A=16

4x=16

x=4

B=5x

B=20

Answer 2

Given,

• A:B =4:5
• A = 16

To find,

• We have to find the value of B.

Solution,

We can simply find the value of B by using the concept of proportion.

It is given that A: B =4:5 and A = 16, then

           A/B = 4/5

          16/B = 4/5

    By cross-multiplying, we get

        16 * 5 = B *4

        16* 5 /4 = B

              20   = B

Hence, A: B =4:5 if A=16 then the value of B is 20.
