What is 10/6 + 6/11?

What is 10/6 + 6/11?

Here's how you add

10
6
+
6
11

Step 1

We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.

Now we multiply 10 by 11, and get 110, then we multiply 6 by 11 and get 66.

10/6 times 11

Now for the second term. You multiply 6 by 6, and get 36, then multiply 6 by 11 and get 66.

6/11 times 6

This gives us a new problem that looks like so:

110
66
+
36
66

Step 2

Since our denominators match, we can add the numerators.

110 + 36 = 146

That gives us an answer of

146
66

Step 3

Can this fraction be reduced?

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

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

146
66
÷ 2 =
73
33

Let's try dividing by that again...

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 33. So we're done reducing.

There you have it! Here's the final answer to 10/6 + 6/11

10
6
+
6
11
=
