What is 96/2 + 6/10?

What is 96/2 + 6/10?

This is how you add

96
2
+
6
10

Step 1

Now we need to make our denominators match.

Since 2 is evenly divided by 10, we can multiply just 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

The problem now has new fractions to add:

480
10
+
6
10

Step 2

Since our denominators match, we can add the numerators.

480 + 6 = 486

This yields the answer

486
10

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

486
10
÷ 2 =
243
5

Let's try dividing by that again...

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...

No good. 7 is larger than 5. So we're done reducing.

There you have it! Here's the final answer to 96/2 + 6/10

96
2
+
6
10
=
243
5
