What is 9/32 + 3/5?

What is 9/32 + 3/5?

Here's how to add

9
32
+
3
5

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 9 by 5, and get 45, then we multiply 32 by 5 and get 160.

9/32 times 5

Now for the second term. You multiply 3 by 32, and get 96, then multiply 32 by 5 and get 160.

3/5 times 32

This gives us a new problem that looks like so:

45
160
+
96
160

Step 2

Since our denominators match, we can add the numerators.

45 + 96 = 141

That gives us an answer of

141
160

Step 3

Can this fraction be reduced?

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

No good. 149 is larger than 141. So we're done reducing.

Congratulations! Here's your final answer to 9/32 + 3/5
