# If 2/3 = x/y, then which of the following must be true?

(2 + x)/3 = (x + 2)/y

3/2 = x/y

(2 + 3)/3 = (x + y)/y

(2 + 1)/3 = (x + 1)/y

**Solution:**

Given expression is

2/3 = x/y

We have the componendo and dividendo principle, which means if a/b = x/y then a + b/b = x + y/y is possibly true.

Here, we have a = 2, b = 3

Therefore, (2 + 3)/3 = (x + y)/y must be true

## If 2/3 = x/y, then which of the following must be true?

**Summary:**

If 2/3 = x/y, then (2 + 3)/3 = (x + y)/y must be true.
