Here's how to add

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 70 by 7, and get 490, then we multiply 51 by 7 and get 357. Now for the second term. You multiply 5 by 51, and get 255, then multiply 51 by 7 and get 357. This gives us a new problem that looks like so:

Step 2Since our denominators match, we can add the numerators. 490 + 255 = 745 So what's the answer so far?
