Definition

A unit fraction is a fraction whose numerator is always 1 and whose denominator is a positive integer.

For example, following are some unit fractions 12, 19, 116, 147 and so on.

Rules to find the product of a unit fraction and a whole number

We first write the whole number as a fraction, i.e., writing it divided by one; for example: 7 is written as 71

We then multiply the numerators

We multiply the denominators

If any simplification is required, it is done and then we write the final fraction.

Problem 1:

What is 12 of 6

Solution

Step 1:

12 of 6 is 12 × 6

Step 2:

First, we write the whole number 6 as a fraction 61

12 × 6 = 12 × 61

Step 3:

As 2 and 6 are multiples of 2, cross cancelling 2 and 6, we get

12 × 61 = 11 × 31

Step 4:

Multiply the numerators and denominators of both fractions as follows.

11 × 31 = (1×3)(1×1) = 31 = 3

Step 5:

So 12 of 6 = 3
