What is 25/36 + 1/3?

What is 25/36 + 1/3?

This is how you add

25
36
+
1
3

Step 1

We have to make sure the denominators are equal.

36 goes into 3 evenly, so we only need to multiply one term to get a common denominator.

Multiply 1 by 12, and get 12, then we multiply 3 by 12 and get 36.

1/3 times 12

This gives us a new problem that looks like so:

25
36
+
12
36

Step 2

Since our denominators match, we can add the numerators.

25 + 12 = 37

That gives us an answer of

37
36

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 29...

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. 37 is larger than 36. So we're done reducing.

And we're done! Here's the final answer to 25/36 + 1/3
