U add 3 to make a whole
2/2 + 3/3 = 1 + 1 = 2
(-1)+(-2)=(-3) (-1)(-2)=2
1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
2/9 + 2/3 = 2/9 + 6/9 = 8/9
They add up to 3/4
4 over 3. In adding fractions, you just add the numerators together if the denominators are the same.

You need to make the denominators the same (the numbers on the bottom). Then you can just add the numerators (the numbers on the top).2 and 3 are factors of 6, so 6 would be the best denominator to aim for.Multiply 1/2 by 3/3 to get 3/6(3/3 is the same as 1. When you multiply something by one you don't change its value.)Multiply 1/3 by 2/2 to get 2/6Now you can add 3/6 + 2/6 because the denominators are the same. The answer is 5/6See the related question below: "How do you add fractions?"
