Question

There are two couches against a wall. If one takes up 4/9 of the wall and the other takes up 1/5 of the wall, how much of the wall is covered by couches? Plz help

Answer 1

20/45 + 9/45 =29/45

45/45 - 29/45
=16/45

16/45 of the wall is covered by couches

Answer 2

29/45
First we have to make them equivalent.
So lets make them equal.
4/9 * 5 is 20/45
1/5 * 9 is 9/45
Add then
20/45 + 9/45 = 29/45
