1 = 9/9
9/9 - 7/9 = 2/9
2 over 63
2/9 minus 5/27 = 1/27
Converting all to ninths, that is 7 over 9 minus 3 over 9 which gives 4 over 9 as the answer.
5/7 − 4/9 = 17/63
Zero.
7/9 − 5/10 = 25/90 which reduces to 5/18
It is nine over seven.
Do you mean is 7/9 > 1? Of course not. It's seven ninths of the whole.
10/5 = M - 9-7 => M = 3 and 2/7 = 23/7
5 over 9.
2/9
+7/9, positive seven over nine.
