What is 63/58 + 4/12?

What is 63/58 + 4/12?

Here's how we add

63
58
+
4
12

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 63 by 12, and get 756, then we multiply 58 by 12 and get 696.

63/58 times 12

Now for the second term. You multiply 4 by 58, and get 232, then multiply 58 by 12 and get 696.

4/12 times 58

This gives us a new problem that looks like so:

756
696
+
232
696

Step 2

Since our denominators match, we can add the numerators.

756 + 232 = 988

That gives us an answer of

988
696

Step 3

Can this fraction be reduced?

First, we attempt to divide it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

988
696
÷ 2 =
494
348

So far so good... let's try to divide by that number again.

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

494
348
÷ 2 =
247
174

So far so good... let's try to divide by that number again.

No good. So next you try the next prime number, which is 167...

No good. So next you try the next prime number, which is 173...

No good. So next you try the next prime number, which is 179...

No good. 179 is larger than 174. So we're done reducing.

And we're done! Here's the final answer to 63/58 + 4/12

63
58
+
4
12
=
