What is 56/60 + 1/10?

What is 56/60 + 1/10?

Let's add

56
60
+
1
10

Step 1

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

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

Multiply 1 by 6, and get 6, then we multiply 10 by 6 and get 60.

1/10 times 6

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

56
60
+
6
60

Step 2

Since our denominators match, we can add the numerators.

56 + 6 = 62

That gives us the sum, which is

62
60

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:

62
60
÷ 2 =
31
30

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...

Nope. Try the next prime number, 13...

Nope. Try the next prime number, 17...

Nope. Try the next prime number, 19...

Nope. Try the next prime number, 23...

Nope. Try the next prime number, 29...

Nope. Try the next prime number, 31...

No good. 31 is larger than 30. So we're done reducing.

Congratulations! Here's your final answer to 56/60 + 1/10
