What is 25/36 + 4/6?

What is 25/36 + 4/6?

Let's add

25
36
 +
4
6

Step 1

We have to make sure the denominators are equal.

36 goes into 6 evenly, so we only need to multiply one term to get a common denominator.

Multiply 4 by 6, and get 24, then we multiply 6 by 6 and get 36.

4/6 times 6

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

25
36
 +
24
36

Step 2

Since our denominators match, we can add the numerators.

25 + 24 = 49

That gives us the sum, which is

49
36

Step 3

Now, do we need to simplify this fraction?

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

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 + 4/6
