## Step 1

We can"t include two fractions with different denominators (the bottom number). Therefore you need to get a usual denominator - both bottom numbers should match. To carry out this, you"ll multiply the platform times every other... Yet the numerators have to change, too. They obtain multiplied through the *other* term"s denominator.

You are watching: 1/3 plus 1/3

So we multiply 1 by 3, and also get 3, then us multiply 7 by 3 and also get 21.

Do the same for the second term. Us multiply 1 by 7, and also get 7, then multiply 7 through 3 and get 21.

So currently our fountain look choose this:

321 |

21 |

## Step 2

Since our denominators match, us can add the numerators.

3 + 7 = 10

Now we have actually an answer.

1021 |

## Step 3

Last of all, we should simplify the fraction, if possible. Have the right to it be diminished to a easier fraction?

To discover out, we try dividing that by 2...

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

Nope! So now we shot the next best prime number, 5...

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

Nope! So currently we try the next best prime number, 11...

No good. 11 is bigger than 10. So we"re excellent reducing.

There you have actually it! Here"s the last answer come 1/7 + 1/317 |
