What is 64/4 + 1/12?

What is 64/4 + 1/12?

Here's how we add

64
4
+
1
12

Step 1

Now we need to make our denominators match.

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

Multiply 64 by 3, and get 192, then we multiply 4 by 3 and get 12.

64/4 times 3

This gives us a new problem that looks like so:

192
12
+
1
12

Step 2

Since our denominators match, we can add the numerators.

192 + 1 = 193

That gives us an answer of

193
12

Step 3

Can this fraction be reduced?

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

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

No good. 13 is larger than 12. So we're done reducing.

There you have it! Here's the final answer to 64/4 + 1/12

64
4
+
1
12
=
193
