Answer: what now sorry don’t know
Step-by-step explanation:
The sum of 44+40 is 84 then the greatest common factor would be 4 because when you divide 84 and 4 you get 21 (the GCF is 4)
FInd the common denominator: 12
That means gianni ate 4/12 of his pizza
Subtract 9/12 by 4/12
You get 5/12
That means 5/12 must be your answer
Richard ate 5/12 of his pizza
Hope this helped
(Answer also can be 5)
Example :
20 + 30.....GCF = 10
10(2 + 3)
The GCF of the number now is 1....because u have basically already factored the GCF out.....leaving only 1 as a factor now
here's another one...
3 + 9...GCF = 3
3(1 + 3)
so the GCF now is 1
