This document discusses unit fractions, which are fractions with a numerator of 1. It explains that for unit fractions, the fraction with the smaller denominator will be greater. This is because as the denominator gets larger, the fraction value gets smaller. Some examples are provided to compare unit fractions and determine which is greater based on the relative size of the denominators.

1. Comparing Unit
Fraction

2. Unit fractions
Unit fractions are fractions having 1 as its numerator.
For example, compare 1/7 and 1/5. One can conclude that 1/5 >
1/7 by observing the diagram.
So, in unit fraction the larger the denominator the smaller
will be the fraction.
Hence, we conclude that if the numerators are the same in
two fractions, the fraction with the smaller denominator is
greater of the two.

3. Example 1: Compare 1/3 and 1/7
Solution:
We know that larger the denominator, the smaller will
be the fraction. Here, 7is greater than 3.

Example 2: Which is lesser? 1/7 or 1/12?
Solution:
We know that larger the denominator, the smaller will be
the fraction. Here, 12 is greater than 7.

Ans: 1/12 is lesser than 1/7
Ans: 1/3 is greater than 1/7

5. Arranging Unit Fractions

7. • As the denominator gets greater in
value, its fraction part becomes
smaller.
• As the denominator gets lesser in
value, its fraction part becomes
greater.
