You have to find the common denominator for the fractions, so multiply the "half" (2) by the "thirds" (3). These two numbers multiplied with give 6 as a common denominator. Then multiply the 1 by the 3, which will give 3/6ths, and the 2 by the other 2, which will give 4/6ths. Hmmm! it seems that 4/6ths is greater than 3/6ths, so you have to add a whole to the 3/6ths to make a big enough fraction to subtract. Doing that will give you 9/6ths and you can subtract the 4/6ths. So the answer would be 5/6ths. Try it.
-8 - (-13) = - 8 + 13 = +5 ( minus a minus is a plus)
12 and 5/6ths converts to 12 and 10/12ths. So 12 and 10/12ths - 7 and 5/12ths = 5 and 5/12ths
13/20 minus 3/5 is 1/20
1 6ths of 30 is equal to 5
12 and 1 half minus 3 and 5 6ths = 8 2/3
The answer is 7/8 minus 5/6 = 1/24
If you mean: 9 and 5/9 minus 6 and 5/6 then it is 2 and 13/18
If you convert both numbers into 6ths it is easier to work out. 1 and 1/2 is 9/6ths and 2/3rds is 4/6ths. so, 9/6ths - 4/6ths = 5/6ths.
-5 - 13 = -18
5/6ths

5 minus -8 is 13.
12 and 5/6ths converts to 12 and 10/12ths. So 12 and 10/12ths - 7 and 5/12ths = 5 and 5/12ths
34/6 + 15/6 = 53/6
It is: 5/6 minus 6/13 = 29/78
