find lowest common denominator which is 20, then times 4/4 to the first fraction to get this 16/20, then on the other fraction
times 5/5 to the fraction 3/4, to get 15/20. Then add 16/20+15/20= 31/20 which equals to 1 11/20
another way to see this
4/4x4/5= 16/20, 5/5x3/4=15/20
16/20+15/20= 31/20 then
31/20= 1 11/20

4/5 + 3/4 = . . . . common denominator = 20
= (4x4 + 5x3) / 20
= (16 + 15 ) /20
= 31/20

4/5= 16/20
3/4= 15/20
