What is 36/4 + 1/8?

What is 36/4 + 1/8?

Here's how to add

36
4
+
1
8

Step 1

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

8 goes into 4 evenly, so we only need to multiply one term to get a common denominator.

Multiply 36 by 2, and get 72, then we multiply 4 by 2 and get 8.

36/4 times 2

This gives us a new problem that looks like so:

72
8
+
1
8

Step 2

Since our denominators match, we can add the numerators.

72 + 1 = 73

That gives us an answer of

73
8

Step 3

Can this fraction be reduced?

First, we attempt to divide 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 8. So we're done reducing.

Congratulations! Here's your final answer to 36/4 + 1/8

36
4
+

8
=
73
