8. What’s the sum of 2/5 and 2/4?

Answer 1

= 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

Answer 2

9/10

Explanation:

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.
