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


(77)/(72) * (9)/(7)


77 * 9 = 693


72 * 7 = 504


= (693)/(504)

Now reduce:


(693)/(504) / 63 = (11)/(8)

(optional) Change into a mixed number:


8 /11 = 1(3)/(8)

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

Hope this helps.

Answer: 1 3/8 or 1 whole and 3/8

Step-by-step explanation: first you do 77/72 multiplied by 9/7 and you get

1 and 189/594 then you simplify and get 1 and 63/168 and you simplify again and you get 1 and 21/56 then you simplify again and get 1 and 3/8

MEANINGS

-SIMPLIFY~WHEN YOU SIMPLIFY YOU DIVIDE THE FRACTION BY A NUMBER DIVISIBLE BY BOTH THE NUMERATOR AND DENOMINATOR

EXAMPLES~ 2/4 YOU SIMPLIFY IT BY DIVIDING BOTH THE NUMERATOR AND DENOMINATOR BOTH BY 2 AND YOU GET 1/2

Hope this helps ♥
