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 ♥

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

[tex]\frac{77}{72} \times \frac{9}{7}[/tex]

[tex]77 \times 9 = 693[/tex]

[tex]72 \times 7 = 504[/tex]

[tex]= \frac{693}{504}[/tex]

Now reduce:

[tex]\frac{693}{504} \div 63 = \frac{11}{8}[/tex]

(optional) Change into a mixed number:

[tex]8 \div11 = 1\frac{3}{8}[/tex]

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

Hope this helps.
