Question

A:B = 6:7 and A=30. Find B.

Please help me out with this, i dont know how to work it out, thank you.​

Answer 1

Explanation:

it is a ratio, and as such it is simply a fraction.

we can also write it

A/B = 6/7

and it gives us the same information.

and so,

30/B = 6/7

30 = 6B/7

210 = 6B

B = 210/6 = 35
