What is 96/2 + 5/10?

What is 96/2 + 5/10?

Let's add

96
2
+
5
10

Step 1

We have to make sure the denominators are equal.

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

Multiply 96 by 5, and get 480, then we multiply 2 by 5 and get 10.

96/2 times 5

This gives us a new problem that looks like so:

480
10
+
5
10

Step 2

Since our denominators match, we can add the numerators.

480 + 5 = 485

That gives us an answer of

485
10

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...

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

485
10
÷ 5 =
97
2

So far so good... let's try to divide by that number again.

No good. 5 is larger than 2. So we're done reducing.

And we're done! Here's the final answer to 96/2 + 5/10

96
2
+
5
10
=
97
2
