2/3 + 3/4 = 17/12 or 1 5/12.

Equation:

?=2/3+3/4

To add fractions, you first must make their denominators (bottom numbers) the same. To do this you have to find the lowest number they can both be divided into. In the case of 3 and 4, it would be 12 (12/3=4, 12/4=3). However, anything you do to the denominator, you must also do to the numerator. So you do this:

2*4=8

3*4=12

3*3=9

4*3=12

which turns the equation into:

?=8/12+9/12

When adding fractions, the denominators always stay the same, and you just add the numerators together.

8+9=17

so the answer would be 17/12

The sum of 2/3 and 3/4 is 1 5/12

3/4+2/3 is the same as 9/12+8/12 = 17/12 or 1 and 5/12 as a mixed number

Normally, to add fractions you would first look for a common denominator. But if the fractions can be simplified, as here, it is actually easier if you simplify them first.
