Question

If a - 3b - 9b - 7a, then ratio of a to b is

A: 3:2
B: 2:3
C: 3:4
D: 4:3

Answer 1

A)
`3:2`

Explanation:

If
`\(a-3b=9b-7a\)` , then

`\(a+7a=9b+3b\)`

`\(8a=12b\)`

`\((a)/(b)=(12)/(8)=(3)/(2)\)`

Hence, the ratio of
`a` to
`b` is
`3:2` .

If , then Hence, the ratio of to is.

If
`a - 3b - 9b - 7a` , then ratio of
`a` to
`b` is

`A: 3:2\\\\B: 2:3\\\\C: 3:4\\\\D: 4:3`
