Check whether the result can be simplified.

If you would like to have a vivid explanation with a detailed example, please read the page Addition Fraction plus Fraction - Pizza Roma with lots of cheese, please!

Step 1: Determine the common denominator:

Nothing to do. The denominators are the same!

Step 2: Expand to the common denominator:

Nothing to do. The denominators are the same!

Step 3: Add the numerators:

Since the two fractions have a common denominator, you can add:

2	+	3	=	2 + 3	=	5
10		10		10		10

Step 4: Check whether the result can be simplified

The result can be simplified by the number 5:

5	=	5 ÷ 5	=	1
