17/9
I thought it was 15/9
8/9 + 4/7 = ((8*7)+(4*9))/(9*7) = 92/63
Expressed as a proper fraction in its simplest form, 7/8 + 1/9 = 71/72
eight over ten
7/8ths
88/99 - 81/99 = 7/99
Your stupid... 2+7-9-8=-8 The 2+7 cancel out the -9, so the answer is -8.
5/8 divided by 7/9 = 45/56
one and seven over twenty 1 7/20
7/20 + 3/9 = 41/60
5/4 + 7/9 = 2 1/36
1/8 + 3/4 = 7/8
137/24 or 517/24
