What is 32/1 + 7/10?

What is 32/1 + 7/10?

Let's add

32
1
+
7
10

Step 1

We have to make sure the denominators are equal.

Since 1 is evenly divided by 10, we can multiply just one term to get a common denominator.

Multiply 32 by 10, and get 320, then we multiply 1 by 10 and get 10.

32/1 times 10

The problem now has new fractions to add:

320
10
+
7
10

Step 2

Since our denominators match, we can add the numerators.

320 + 7 = 327

This yields the answer

327
10

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing it by 2...

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. So next you try the next prime number, which is 11...

No good. 11 is larger than 10. So we're done reducing.

And we're done! Here's the final answer to 32/1 + 7/10
