Question

What is X if X + 2/3 = 9/10?

Answer 1

`x=(7)/(30)`

Explanation:

Given the following question:


`x+(2)/(3) =(9)/(10)`

In order to find the answer to this question we need to subtract 9/10 from 2/3. To do this we need to find the common denominator, and then subtracting the numerators.


`(9)/(10) -(2)/(3)`

`(9)/(10) *3=(27)/(30)`

`(2)/(3) *10=(20)/(30)`

`27-20=7=(7)/(30)`

`x=(7)/(30)`

Hope this helps.
