A whole number can be treated as a fraction too, by giving it a denominator #1#.

Explanation:

A whole number can be expressed as a fraction by giving it a denominator #1#.

For example #3 = 3/1#.

Then to add two fractions, you need to give them a common denominator, so multiply the numerator and denominator of our newly created fraction by the denominator of the original fraction. Then you can add the numerators, as follows:

#3+2/5 = 3/1+2/5 = (3*5)/(1*5) + 2/5 = 15/5 + 2/5 = (15+2)/5 = 17/5#
