**About:**

The **unitary method** is a technique which is used for solving a problem by finding the value of a single unit, i.e., 1, (by dividing) and then finding the necessary value by multiplying the single unit value.

It is used to find the value of a unit from the value of a multiple, and hence the value of a multiple .

In unitary method it is not always necessary to find the value of single unit

**DEMONSTRATION:**

A man walks 6 miles in 2 hours. How far does he walk in 5 hours?

Calculate how far the man can walk in 1 hour.

Therefore, dividing by 2, the man walks 3 miles in 1 hour.

Multiplying by 5 for 5 hours, the man walks 5 x 3 =15 miles

Let us consider the distance travelled by man be X

Now divide X by given distance that is 6, so (x/6)

it is equal to time taken to travel X distance that is 5 hours

Time taken to travel 6 miles is 2 hours hence divide 6 by 2 (6/2)

Therefore x/6=5/2

Hence X=15 miles.
