Question

What number should be added to -3/5 to get 2/3.​

Answer 1

19/15 should be added to -3/5 to get 2/3

(19/15 is the answer)

Explanation:

Let the number be x,

Now, we know that once we add x to -3/5, we get 2/3, or in equation form,

-3/5 + x = 2/3

We solve this for x,

`-3/5 + x = 2/3\\x = 2/3 + 3/5\\x = 10/15 + 9/15\\x = (10+9)/15\\\\x = 19/15\\`

So, the number is 19/15
