This is 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 40 by 10, and get 400, then we multiply 41 by 10 and get 410. Do the same for the second term. We multiply 3 by 41, and get 123, then multiply 41 by 10 and get 410. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 400 + 123 = 523 The sum we get is
