Here's how we add

Step 1Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator. Now you multiply 63 by 7, and get 441, then we multiply 58 by 7 and get 406. Do the same for the second term. We multiply 2 by 58, and get 116, then multiply 58 by 7 and get 406. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 441 + 116 = 557 This yields the answer
