( 5x4 y4 −−−−−−√ ) ( 6x2y−−−−√ )
The GCF is 3.It is: 3
1 and 3 can go into 12 and 63.
12 with 3 remaining 63 - 3 = 60 = 5 x 12
3. 63 ÷ 5 = 12 r 3
63 - 3 = 60 = 5 x 12 12 times with 3 remaining
If you are meaning 12/63, 3 can go into both (a good trick is to add the digits separately 1+2=3 and 6+3=9, if the answer is a multiple of 3 then 3 goes into it) So therefore 4/21 is 12/63 simplified.

1, 2, 3, 4, 6, 12 1, 3, 7, 9, 21, 63
There are 12 inches in one foot. Therefore, 63 inches is equal to 63/12 = 5 remainder 3 or 5 feet 3 inches.
1/5 of 63 is 12 3/5 or 12.6
3*N + 12 = 63 or 3*(N + 12) = 63 From the wording, the first is more likely but it gives rise to a fractional solution. If you are at a stage where you are learning to generate such equations, fractional answers are less likely.
Expressed as a mixed number in its simplest form, 63/5 is equal to 12 3/5 or twelve and three fifths.
