Adding Fractions with Mutual Denominators
When adding fractions with mutual denominators, you automatically keep the mutual number as your denominator in your solution. To determine the numerator for your solution, you must add the two numerators in the problem.
4/15 + 7/15 = ??
1. Both denominators are 15, so 15 will be the denominator in your solution. ( ??/15 )
2. To get numerator, we must add 4+7 which comes out to be 11.
Now we have our final solution which is 11/15.
