The problem here is to add and|
These two fractions do not have the same denominators (lower numbers), so we must first find a common denominator of the two fractions, before adding them together.

For the denominators here, the 8 and 14, a common denominator for both is 56. With the common denominator, the
becomes a
and the
becomes a
So now our addition problem becomes this...

Since these two fractions have the same denominators (the numbersunder the fraction bar), we can add them together by simply adding the numerators (the 21 and 36 = 57), while keeping the same denominator (the 56).

The fraction is an improper fraction (the numerator is greater than the denominator). While there is nothing incorrect about this, an improper fraction is typically simplified further into a mixed number.

The whole number part of the mixed number is found by dividing the 57 by the 56. In this case we get 1.
The fractional part of the mixed number is found by using the remainder of the division, which in this case is 1 (57 divided by 56 is 1 remainder 1). The final answer is: |

Since these two fractions have the same denominators (the numbersunder the fraction bar), we can add them together by simply adding the numerators (the 20 and 21 = 41), while keeping the same denominator (the 36).

And, we just add the whole number parts, or 7 + 2 = 9.
