Question

Which expression is equivalent to
-21/4over -2/3

Answer 1

`(9)/(4)/(3)/(2)`

Explanation:

`-2(1)/(4)` is equilavalent to
`-(9)/(4\\)`.

`-(2)/(3)` can stay put.

The equation is division so neither answers #2 and #3 are the correct ones because when dividing fractions the second fraction has to be flipped in order to continue multiplying instead.

In addition, when two negatives are put together the answer must always be positive.

Hence the answer is
`(9)/(4)/(3)/(2)`.
