Step 1

Of course, friend can"t add two fractions if the platform (bottom numbers) don"t match. To gain a typical denominator, multiply the denominators together. Climate we fix the numerators by multiplying each one by their various other term"s denominator.

You are watching: 1 1/3 plus 1 1/3

Now you multiply 1 by 3, and also get 3, then we multiply 5 by 3 and get 15.

*

Do the same for the second term. Us multiply 1 by 5, and also get 5, then multiply 5 by 3 and also get 15.

*

The problem now has new fractions to add:

3
15
+5
15

Step 2

Since our denominators match, us can include the numerators.

3 + 5 = 8

This yields the answer

8
15

Step 3

The last action is to minimize the fraction if us can.

To uncover out, we shot dividing it by 2...

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

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

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

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

No good. 11 is larger than 8. So we"re done reducing.

Congratulations! Here"s your last answer to 1/5 + 1/31
5
+1

=8
