What is 96/2 + 7/10?

What is 96/2 + 7/10?

This is how we add

96
2
+
7
10

Step 1

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

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

We now have a new problem, that looks like this:

480
10
+
7
10

Step 2

Since our denominators match, we can add the numerators.

480 + 7 = 487

Answer:

487
10

Step 3

Now, do we need to simplify this fraction?

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 10. So we're done reducing.

Congratulations! Here's your final answer to 96/2 + 7/10

96
