9/10 - 2/5 = In order to add or subtract fractions, they must have the same denominator. 9/10 - (2/2)(2/5) = 9/10 - 4/10 = 5/10 = 1/2
9/10
If the base is the same, you can subtract the exponents. For example (using "^" por powers):10^5 / 10^2 = 10^310^5 / 10^(-4) = 10^9
The idea is to subtract 1/2 minus 9/10 (or the other way round).
-1/9
11/40
4/9 just subtract the numerators because the denominators are the same.
9/10 - 4/5 = 9/10 - 8/10 = 1/10
9/10 − 4/5 = 1/10
12/11 = 108/99 10/9 = 110/99 10/9 - 12/11 = 2/99 12/11 - 10/9 = -2/99
4/10 / 5/9 = 4/10 * 9/5 = 36/50 = 18/25
9/10 + 4/5 = 9/10 + 8/10 = 17/10 = 1 7/10
4/9 divided by 3/10 is 1.4814
(4/9)/(9/10) = 4/9 * 10/9 = 40/81.
