What is 56/60 + 8/12?

What is 56/60 + 8/12?

This is how we add

56
60
+
8
12

Step 1

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

Since 12 is evenly divided by 60, we can multiply just one term to get a common denominator.

Multiply 8 by 5, and get 40, then we multiply 12 by 5 and get 60.

8/12 times 5

So now our fractions look like this:

56
60
+
40
60

Step 2

Since our denominators match, we can add the numerators.

56 + 40 = 96

So the answer is:

96
60

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

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:

96
60
÷ 2 =
48
30

Now, try the same number again.

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

48
30
÷ 2 =
24
15

Now, try the same number again.

Nope. Try the next prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

24
15
÷ 3 =
8
5

Now, try the same number again.

Nope. Try the next prime number, 5...

Nope. Try the next prime number, 7...

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

Congratulations! Here's your final answer to 56/60 + 8/12
