5/12 - 4/12 = 1/12
13/20 - 3/5 = 13/20 - 12/20 = 1/20
5/9 − 5/12 = 5/36
To subtract fractions, the first step is to make sure both fractions have the same denominator. For 5/12 and 1/4, this can be achieved by multiplying top and bottom of the latter fraction by 3, giving us 3/12. Now the question says 5/12 - 3/12 and all you have to do is subtract the numerators. That gives us the answer 2/12 which can then be simplified to 1/6.
5/12
16/5 or 3.2
2/3 - 1/4 = 8/12 - 3/12 = 5/12
Subtract 7/24 from 4/8 to get 5/244/8 * 3/3 = 12/2412/24 -5/24 = 7/24
5/9-1/3 is the same as 5/9-3/9. This would then subtract out to be 2/9. (2 over 9)
