 What is 6/11 + 1/7? 6 11
+
 1 7

Step 1

We 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 6 by 7, and get 42, then we multiply 11 by 7 and get 77. Now for the second term. You multiply 1 by 11, and get 11, then multiply 11 by 7 and get 77. This gives us a new problem that looks like so:

 42 77
+
 11 77

Step 2

Since our denominators match, we can add the numerators.

42 + 11 = 53

That gives us an answer of

 53 77

No good. 59 is larger than 53. So we're done reducing.
