Answer:
Since we're adding fractions with different denominators, we need to find a common one. In this case that would be 56.
Explanation:
Then, you have to multiply each denominator by how much it took to get to 56 and you have to multiply the numerator by the same number as well. So, we have 21/56 for our first fraction and 16/56 for the second. Then, all you have to do is add them together but the denominator stays the same. 21 + 16 = 37.
3 x 7 = 21 2 x 8 = 16

8 x 7 = 56 7 x 8 = 56
The final answer will be 37/56
Hope this helps! Have an amazing day!
