What is 10/3 + 5/10?

Here's how to add

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 10 by 10, and get 100, then we multiply 3 by 10 and get 30.

Do the same for the second term. We multiply 5 by 3, and get 15, then multiply 3 by 10 and get 30.

So now our fractions look like this:

Step 2

Since our denominators match, we can add the numerators.

100 + 15 = 115

Now we have an answer.

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...

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...

No good. 7 is larger than 6. So we're done reducing.

Congratulations! Here's your final answer to 10/3 + 5/10
