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 4 by 6, and get 24, then we multiply 7 by 6 and get 42. Do the same for the second term. We multiply 1 by 7, and get 7, then multiply 7 by 6 and get 42. The problem now has new fractions to add:


Step 2Since our denominators match, we can add the numerators. 24 + 7 = 31 This yields the answer


Step 3The last step is to reduce the fraction if we can. To find out, we try dividing it by 2... Nope! So now we try the next greatest prime number, 3... Nope! So now we try the next greatest prime number, 5... Nope! So now we try the next greatest prime number, 7... Nope! So now we try the next greatest prime number, 11... Nope! So now we try the next greatest prime number, 13... Nope! So now we try the next greatest prime number, 17... Nope! So now we try the next greatest prime number, 19... Nope! So now we try the next greatest prime number, 23... Nope! So now we try the next greatest prime number, 29... Nope! So now we try the next greatest prime number, 31... Nope! So now we try the next greatest prime number, 37... No good. 37 is larger than 31. So we're done reducing. There you have it! Here's the final answer to 4/7 + 1/6
