Okay so this is how you solve this.   4/5 + 4/7 = you can't do that so you gotta find the same bottom.   you find the same bottom by multiplying 5 and 7 which equals 35  the you times the top by it's opposite.  4*7 and 4*5 = 28, ,20  you answer is  28/30 + 20/30 now you just simply add  28+ 20 = 48  it'll be an improper faction 48/35

4/5 + 4/7 = 1 13/35 since  4/5 + 4/7 = (4x7) + (5x4)/5x7 =48/35 = 1 13/35 (hope this helps.)
