What is 1/5 plus 3/4 equal too?

1/5=4/20

3/4=15/20

4/20+15/20

=19/20

1/5 + 3/4 ... First you have to match the bottom numbers so you multiply the bottom numbers and you get 20. So you do 20/5 and its 4. You multiply it with the which you get 4, and get a fraction of 4/20 (originally 1/5) then you do the same thing for the second number except you do 20/4 which is 5. Then you multiply it with 3 and you get 15 (3x5=15). Then you put that fraction together which is 15/20 (originally 3/4) and put the two fractions together to add.

4/20+15/20=19/20. Therefore, 1/5+3/4=19/20
