What is 3/64 + 5/9?

What is 3/64 + 5/9?

Here's how we add

3
64
+
5
9

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 3 by 9, and get 27, then we multiply 64 by 9 and get 576.

3/64 times 9

Now for the second term. You multiply 5 by 64, and get 320, then multiply 64 by 9 and get 576.

5/9 times 64

This gives us a new problem that looks like so:

27
576
+
320
576

Step 2

Since our denominators match, we can add the numerators.

27 + 320 = 347

That gives us an answer of

347
576

Step 3

Can this fraction be reduced?

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

No good. 349 is larger than 347. So we're done reducing.

There you have it! Here's the final answer to 3/64 + 5/9

3
