Multiply the fractions 9 over 7 × 63 over 81

1 answer:

8 0

(9/7) x (63/81) = 567/567 = 1.

This was found by multiplying the first numbers (from each fraction) together and then the last numbers (from each fraction) together and putting a / between them. The simplification step was done by finding they are the same. This means that they always multiply to one.
