Formula
We multiply the fractions so that the second fraction numbers are in inverse (mean: the first fraction remained the same, the second fraction reversed, the numerator becomes denominator and the denominator becomes numerator).
| a |
| b |
| c |
| d |
| a x d |
| b x c |
Example:
| 4 |
| 6 |
| 6 |
| 12 |
Reverse the numbers of the second fraction, then multiply the numerators together and the denominators together.
| 4 |
| 6 |
| 6 |
| 12 |
| 4 x 12 |
| 6 x 6 |
| 48 |
| 36 |
