Step 1Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term. So, we multiply 63 by 10, and get 630, then we multiply 58 by 10 and get 580. Now for the second term. You multiply 4 by 58, and get 232, then multiply 58 by 10 and get 580. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 630 + 232 = 862 That gives us the sum, which is

Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

So now we try the next greatest prime number, 283... Nope! So now we try the next greatest prime number, 293... No good. 293 is larger than 290. So we're done reducing. There you have it! Here's the final answer to 63/58 + 4/10
