21/2
34-17 times 2 28-7 times 2 times 2 63-7 times 3 times 3
7.875. 21*3=63. 63/8=7.875.
6/63=3(2)/3(21)=2/21 2/21 times.
42/63 = 2/3
42/63 = 2/3
63/42 = 3/2
(63/7) / (22/14) = (63/11) meaning that it equals 63 over 11
They are: 3/7 and 2/9 are the equivalent 27/63 and 14/63
2/3
63 / 84 = (3*3*7) / (2*2*3*7) cancelling out 3*7 leaves 3 / (2*2) = 3/4
2/3
3/5 x 105 = 63
