What is 96/2 + 7/8?

What is 96/2 + 7/8?

Let's add

96
2
+
7
8

Step 1

We have to make sure the denominators are equal.

8 goes into 2 evenly, so we only need to multiply one term to get a common denominator.

Multiply 96 by 4, and get 384, then we multiply 2 by 4 and get 8.

96/2 times 4

This gives us a new problem that looks like so:

384
8
+
7
8

Step 2

Since our denominators match, we can add the numerators.

384 + 7 = 391

That gives us an answer of

391
8

Step 3

Can this fraction be reduced?

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

And we're done! Here's the final answer to 96/2 + 7/8

96
2
+
7
8
=
391
