Answer:
= 9/10
Explanation:
2/5 * 1 = 2/5
1 = 4/4
2/5 * 4/4 = 8/20
2/5 = 8/20
2/4 * 1 = 2/4 * 5/5 = 10/20
2/4 = 10/20
then:
2/5 + 2/4 = 8/20 + 10/20 = (8+10) / 20 = 18/20
18/20 = 9/10
9/10
If you make the denominators same, for example:
2/5 = 8/20 and 2/4 = 10/20, you will be able to add them easily.
add them together, you will get 18/20, and if you simplify them, you will get 9/10.
