7 over 9 = 0.777 . . .
0.875
It's not.20/24 is 4.76% less than 7/8.21/24 = 7/8
14/16, 21/24, 28/32
3 and 16/24
16/20 = 8/10 = 4/5; 21/24 = 7/8
(7/8) - (3/8) / (9/1) = (7/8) - (3/8)*(1/9) = (7/8) - (1/24) = 21/24 - 1/24 = 20/24 = 5/6
The common denominator is 72, so 5/18 = 20/72, and 7/24 = 21/72. Now you can subtract the numerators [20-21 = -1]. So the answer is -1/72.
24 over 7
7/8-1/24=(21-1)/24=20/24=10/12=5/6=0.8333....
7/8 = 21/24 7/12 = 14/24 21/24 - 14/24 = 7/24
5/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/245/6 + 7/8 = 20/24 + 21/24 = 41/24 or 117/24
