The only way you can add or subtract fractions is if they have the same denominator.

Think of money. A half dollar is the same as 50 cents, right?

Think of a pizza. If you divide it into 10 equal pieces, and eat 5 of them, you've eaten 1/2 a pizza.

I hope that makes it clearer.

5/10 + 1/10 = 6/10
