why unit fraction is important

Solution

Def:    A fraction with 1 as its numerator.

Ex: 1/2, 1/3, 1/4 ........

Defining fractions in terms of unit fractions avoids a major conceptual

problem, namely, establishing that a fraction is a number. That burden now

falls to unit fractions. A second advantage of defining fractions in terms of

unit fractions is that this approach separates the study of the numerator and the

denominator of a fraction. Numerators are standard counting numbers, while

denominators are a totally new quantity—they are units defined in terms of

reciprocals. Again, this is the reason we focus in the rest of the article on unit

fractions and units generally.
