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 78 by 10, and get 780, then we multiply 73 by 10 and get 730. Do the same for the second term. We multiply 1 by 73, and get 73, then multiply 73 by 10 and get 730. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 780 + 73 = 853 This yields the answer
