get the least common multiple of 5 and 4 which is 20.So for the first faction get 4 * 4 and 5 * 4 which makes the first fraction 16/20. Then for the second fraction get 3 * 5 and 4 * 5 which makes the fraction 15/20. then jsut add them. So the now the fraction is 31/20. Then simplify it by getting 31 divided by 20 which is 1and 11/20. That is the final answer

Firstly, to add two fractions with different denomenators, you must find their lowest common denomenator:
the common den. of 5 and 4 is 20, so you must multiply the nomenator & denomenator by the same number:
4/5 * 4/4 = 16/20 & 3/4 * 5/5 = 15/20, then you can add:
16/20 + 15/20 = 31/20
And finally simplify:
1 11/20
That's your answer!

3/4 + 5/10 + 6/18 = 3/4 + (5 ÷ 5)/(10 ÷ 5) + (6 ÷ 6)/(18 ÷ 6) = 3/4 + a million/2 + a million/3 = (3 x 3)/(4 x 3) + (a million x 6)/(6 x 2) + (a million x 4)/(3 x 4) = 9/12 + 6/12 + 4/12 = 19/12 = (12 + 7)/12 = 12/12 + 7/12 = a million 7/12

find the least common denominator
in this case i belive its 20
so 4/5 = 16/20
and 3/4 = 15/20
therefore 31/20 or simplified 1 11/20
