7/10 minus 9/8 = -17/40 in its lowest terms
9/10 minus 7/8 is 1/40
It depends: 7/8/9/10 can be: 7/(8/(9/10)) = 7/(80/9) = 63/80, or 7/((8/9)/10) = 7/(8/90) = 7/(4/45) = 315/4 (7/8)/(9/10) = 70/72 = 35/36 (7/(8/9))/10 = (63/8)/10 = 63/80 ((7/8)/9)/10 = (7/72)/10 = 7/720 * * * * * There is an "and" between 8 and 9 so the question, in fact, refers to 7/8 + 9/10 which is not ambiguous. 7/8 + 9/10 = 35/40 + 36/40 = 71/40 = 1 and 31/40
9 - 3/10 = 8 and 7/10
7/8
9/10 + 4/5 = 9/10 + 8/10 = 17/10 = 1 7/10
(7/9) / (9/10) = (7/9) * (9/10) = 7/10 = 0.7
7/8 + 9/10 Easy in decimal, .875 + .9 = 1.775 35/40 + 36/40 = 71/40 = 1 and 31/40
7/8 is smaller than 9/10. 7/8 = .875 whereas 9/10 = .9
If you mean: 7/10, 7/9 and 7/8 then it is 7/8, 7/9 and 7/10 from greatest to least
4/5 = 0.8 5/7 ≈ 0.71 8/9 ≈ 0.89 10/12 ≈ 0.83 11/12 ≈ 0.92 Thus, the greater is 11/12. 11/12, 8/9, 10/12, 4/5, and 5/7.
10+9-8-7+6 = 10
7 over 9 and 8 over 9.
