`\dfrac{N1}{D1} \div \dfrac{N2}{D2} = {?}`

NUMERATOR / DENOMINATOR

Dividing by a fraction is the same as multiplying by the reciprocal of the fraction.

The reciprocal of `\dfrac{N2}{D2}` is `\dfrac{D2}{N2}`.

Therefore:

`\dfrac{N1}{D1} \div \dfrac{N2}{D2} = \dfrac{N1}{D1} \times \dfrac{D2}{N2}`

`\phantom{\dfrac{N1}{D1} \times \dfrac{D2}{N2}} = \dfrac{N1 \times D2}{D1 \times N2}`

`\phantom{\dfrac{N1}{D1} \times \dfrac{D2}{N2}} = \dfrac{NUMERATOR}{DENOMINATOR}`
