Question

Multiply 77/72 by 9/7 in lowest terms

Answer 1

To multiply fractions you have to move to the left so multiply the numerator by the numerator and the denominator by the denominator.

$\frac{77}{72} \times \frac{9}{7}$

$77 \times 9 = 693$

$72 \times 7 = 504$

$= \frac{693}{504}$

Now reduce:

$\frac{693}{504} \div 63 = \frac{11}{8}$

(optional) Change into a mixed number:

$8 \div11 = 1\frac{3}{8}$

The answer is "1 3/8 or 11/8."

Hope this helps.
