What is 25/9 + 4/6?

What is 25/9 + 4/6?

This is how you add

25
9
 +
4
6

Step 1

We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 25 by 6, and get 150, then we multiply 9 by 6 and get 54.

25/9 times 6

Do the same for the second term. We multiply 4 by 9, and get 36, then multiply 9 by 6 and get 54.

4/6 times 9

So now our fractions look like this:

150
54
 +
36
54

Step 2

Since our denominators match, we can add the numerators.

150 + 36 = 186

Now we have an answer.

186
54

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

186
54
 ÷ 2 =
93
27

So far so good... let's try to divide by that number again.

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

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

93
27
 ÷ 3 =
31
9

So far so good... let's try to divide by that number again.

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. 11 is larger than 9. So we're done reducing.

And we're done! Here's the final answer to 25/9 + 4/6
