What is 22/60 + 3/4?

What is 22/60 + 3/4?

Here's how you add

22
60
+
3
4

Step 1

We have to make sure the denominators are equal.

60 goes into 4 evenly, so we only need to multiply one term to get a common denominator.

Multiply 3 by 15, and get 45, then we multiply 4 by 15 and get 60.

3/4 times 15

This gives us a new problem that looks like so:

22
60
+
45
60

Step 2

Since our denominators match, we can add the numerators.

22 + 45 = 67

That gives us an answer of

67
60

Step 3

Can this fraction be reduced?

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

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. So next you try the next prime number, which is 11...

No good. So next you try the next prime number, which is 13...

No good. So next you try the next prime number, which is 17...

No good. So next you try the next prime number, which is 19...

No good. So next you try the next prime number, which is 23...

No good. So next you try the next prime number, which is 31...

No good. So next you try the next prime number, which is 37...

No good. So next you try the next prime number, which is 41...

No good. So next you try the next prime number, which is 43...

No good. So next you try the next prime number, which is 47...

No good. So next you try the next prime number, which is 53...

No good. So next you try the next prime number, which is 59...

No good. So next you try the next prime number, which is 61...

No good. 61 is larger than 60. So we're done reducing.

And we're done! Here's the final answer to 22/60 + 3/4
