Unit Fractions: Definition with Examples

Unit fractions are fractions that have 1 as the numerator and any whole number as the denominator. Some examples of unit fractions can be 1/2, 1/4, 1/25, 1/100 and so on. Some graphical representations of unit fractions are shown in the following image:

Difference Between Unit Fractions and Non-Unit Fractions

Non-unit fractions are fractions that have a numerator value greater than 1. The primary differences between these two types of fractions are as follows:

  1. Unit fractions have a numerator of 1. On the other hand, non-unit fractions have a numerator greater than 1.
  2. The value of unit fractions is always less than or equal to 1 but the value of non-unit fractions can be greater or less than or equal to 1.
  3. Arithmetic operations such as addition, and subtraction are easier for unit fractions compared to non-unit fractions. For instance, if we want to add 1/2 and 1/3, we need to find a common denominator 6, and add the alternate denominators 5 and 6. But, if we want to add two non-unit fractions such as 5/6 and 7/4, we need to find the common denominator, multiply alternate denominators with the individual numerator values and then add the numerator values.

Dividing Whole Numbers By Unit Fractions: Step Wise Analysis

Step 1:

Change the Whole Number into a Fraction At first, we convert the whole number into a fraction by putting 1 in the denominator. This will help us in our division process avoiding mistakes of operations such as multiplication. For instance, if the whole number is 3, we simply write it down as 3/1 and convert it into a fraction.

Step 2:

Swap the Numerator and Denominator and Change the Operator The next step is to change the division operator into a multiplication operator and swap the numerator with the denominator of the fraction, that is, making the existing fraction reciprocal. For instance, for the expression 3÷1/5, we change it to 3/1 x 5/1.

Step 3:

Multiply the Numerators and Denominators After swapping the numerator and denominator and changing the operator, we multiply the numerators and denominators separately and find the result. For the given example of 3/1 x 4/1, we will get the result 20/1 or 20.

Step 4:

Simplify This step is not required for dividing whole numbers by unit fractions as the denominator is always 1. For division by non-unit fractions, we might have to simplify the fraction into its non- divisible digits. For instance, if the expression was 3÷3/5, where 3/5 is the non-unit fraction, then the result would have been like the expression 3/1 x 5/3 = 15/3. Now, 15/3 has the common multiple 3. So, after simplification, the result would be 5/1 or 5.
