Here's how we add
|
|||||||||||
Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 100 goes into 5 evenly, so we only need to multiply one term to get a common denominator. Multiply 1 by 20, and get 20, then we multiply 5 by 20 and get 100. This gives us a new problem that looks like so:
|
|||||||||||
Step 2Since our denominators match, we can add the numerators. 87 + 20 = 107 That gives us an answer of
