What is 96/2 + 8/9?

What is 96/2 + 8/9?

This is how we add

96
2
+
8
9

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 96 by 9, and get 864, then we multiply 2 by 9 and get 18.

96/2 times 9

Now for the second term. You multiply 8 by 2, and get 16, then multiply 2 by 9 and get 18.

8/9 times 2

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

864
18
+
16
18

Step 2

Since our denominators match, we can add the numerators.

864 + 16 = 880

Answer:

880
18

Step 3

Now, do we need to simplify this fraction?

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

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

880
18
÷ 2 =
440
9

Now, try the same number again.

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 9. So we're done reducing.

Congratulations! Here's your final answer to 96/2 + 8/9

96
2
+
8
9
=
440
9
