Question

The number which is subtracted from `(-6)/11` to get `8/9` is __________

Options

• `34/99`

• `(-142)/99`

• `142/99`

• `(-34)/99`

Answer 1

`(-142)/99`

Explanation;

Hint:

Let x be the number to be subtracted

`(-6)/11 - x = 8/9`

`(-6)/11 - 8/9` = x

x = `((-6 xx 9) + (-8 xx 11))/(11 xx 9)`

= `(-54 + (- 88))/99`

= `(- 142)/99`
