 Adding fractions with the same fractional unit or denominator

Example: Find the sum of 2/5 and 1/5.

Answer: Let us represent both using the rectangular strips. In both fractions,
the fractional unit is the same 1/5.

So 2/5 will be represented as:

And 1/5 will be represented as:

Adding the two given fractions is the same as finding out the total number of

shaded parts, each of which represent the same fractional unit 1/5.

Therefore, 2/5 + 1/5 = 3/5
