What is 55/55 + 7/10?

Let's add

Step 1

Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term.

So, we multiply 55 by 10, and get 550, then we multiply 55 by 10 and get 550.

Now for the second term. You multiply 7 by 55, and get 385, then multiply 55 by 10 and get 550.

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

Step 2

Since our denominators match, we can add the numerators.

550 + 385 = 935

That gives us the sum, which is

Step 3

Now, do we need to simplify this fraction?

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

Nope. Try the next prime number, 3...

Nope. Try the next prime number, 5...

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

Now, try the same number again.

Nope. Try the next prime number, 7...

Nope. Try the next prime number, 11...

Are both the numerator and the denominator evenly divisible by 11? Yes! So we reduce it:

Now, try the same number again.

No good. 11 is larger than 10. So we're done reducing.

Congratulations! Here's your final answer to 55/55 + 7/10
