this is a question of ratio proportion and unitary method

Dear Student!

Here is the answer to your query.

 

Unitary method is the method of finding the value of a single unit (object) at first and the finding the value of required number of unit. We can use unitary method for decimals in the same way as the use it for whole numbers.

 

Example :

The cost of 3 shirts is Rs 630.75 . How many shirts can be purchased with Rs 1471.75?

In the above question, first of all we have to find the number of shirts that can be purchased for Rs 1 (Single unit of money) then we can calculate the number of shirts that can be purchased for the given amount

Number of shirts purchased with Rs 630.75 = 3

⇒ Number of shirts purchased with Rs 1 =

 

Thus 7 shirts can be purchased with Rs 1471.75

 

Cheers!
