What is 32/1 + 3/10?

What is 32/1 + 3/10?

Here's how we add

32
1
+
3
10

Step 1

Our denominators (bottom numbers) don't match, so we can't add yet.

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
+
3
10

Step 2

Since our denominators match, we can add the numerators.

320 + 3 = 323

The sum we get is

323
10

Step 3

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

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

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

Nope. Try the next prime number, 11...

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

Congratulations! Here's your final answer to 32/1 + 3/10
