Step 1We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator. Now we multiply 78 by 11, and get 858, then we multiply 73 by 11 and get 803. Now for the second term. You multiply 7 by 73, and get 511, then multiply 73 by 11 and get 803. This gives us a new problem that looks like so:

Step 2Since our denominators match, we can add the numerators. 858 + 511 = 1369 That gives us an answer of
