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

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.

three fourths
Eight and three fourths plus six and two fifths is fifteen and one twentieth.
three and one fourth
Three fourths plus five fourths is equal to eight fourths, or two whole units.
