What is 25/36 + 2/12?

What is 25/36 + 2/12?

Here's how you add

25
36
+
2
12

Step 1

Now we need to make our denominators match.

36 goes into 12 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 3, and get 6, then we multiply 12 by 3 and get 36.

2/12 times 3

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

25
36
+
6
36

Step 2

Since our denominators match, we can add the numerators.

25 + 6 = 31

Answer:

31
36

Step 3

Now, do we need to simplify this fraction?

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

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

Nope! So now we try the next greatest prime number, 17...

Nope! So now we try the next greatest prime number, 19...

Nope! So now we try the next greatest prime number, 23...

Nope! So now we try the next greatest prime number, 29...

Nope! So now we try the next greatest prime number, 31...

Nope! So now we try the next greatest prime number, 37...

No good. 37 is larger than 31. So we're done reducing.

There you have it! Here's the final answer to 25/36 + 2/12
