Question

What is b if `11/12 + b= 5/6`?

Answer 1

`b =color(green)( -1/12`

Explanation:

Transposing `11/12` to the right hand side, we get

`b = 5/6 - 11/12`

The fraction `5/6` can also be written as `10/12` after multiplying its numerator and denominator with 2

`b = 10/12 - 11/12`

`b = (10-11)/12`

`b =color(green)( -1/12`
