Divide the two number by their highest common factor, which is 12. That gives you 3 over 5.
1÷5-1÷4 = (4-5)÷20 =-1÷20
im sorry but i THINK you cannot do that. think about it: 75/20 we do 75 first; whats half of 5? you can't do it.. whats half of 7? you cant do it, but if you do it in tenths like whats half of 70. but it will not work. now 20. whats half of 0.. nothing. whats half of 2? 1. but that wont work. So my estimate would be around; 15/8.
5/6 − 3/10 = 8/15
13/20 - 3/5 = 13/20 - 12/20 = 1/20
If you mean: 8/20 then it is 2/5
180/50 = 18/5 = 33/5

whats 5\7 times 4
-3/20 - 5/4 = -3/20 - 25/20 = -28/20 = -7/5
If you have 5 over 100, divide both numbers by 5. (5/5) / (100/5) = 1/20
No. 2/5 with the denominator of 20 would be 8/20.
20/5 = 4
13/20 - 3/5 = 13/20 - 12/20 = 1/20
(20/5)/(20/9) is the same as (20/5)X(9/20) This can be reduced to (1/5)X(9/1) 9/5.
