Yes because 56/63 = 8/9 in its lowest terms
8/9
63
divide both by the highest factor (8 in this case) answer is 8 over 7
63...so it would be 56/63 and 36/63
36/63 + 56/63 = 92/63 or 1 and 29/63
9/8 or 11/8
1.125 or 1 1/8
1/7 (one over seven. divide the 8 and 56 by 8).
= 1.31746032 8/9 + 3/7 = 56/63 + 27/63 = 83/63 = 1 20/63 (or 1.31746 in decimal form).
The GCF is "7"... for 63 and 56 7 x 8 = 56 7 x 9 = 63
You can divide 24/63 by 3 so it would simplify to 8/21.
