Question

Javed was given $\dfrac{5}{7}$ of a basket of oranges. What fraction of orange was left in the basket?

Answer 1

Hint: Total number of anything in percentage form is 100% and in fraction form is 1. In this problem we are using the same approach to solve. To solve it first we let the total number of oranges in the basket be 1 then, we subtract the number of oranges given to javed.
So, we will find the number of oranges remaining in the basket.

Complete step-by-step answer:
There was 1 orange present in the basket,
It is said that Javed was given a fraction of $\dfrac{5}{7}$ of a basket of oranges.
So the fraction of orange that would be left in the basket = Fraction form of total oranges in the basket of oranges – Fraction of orange that was given top Javed.
keep value in it we get,
Fraction of orange that would be left in the basket = $1 - \dfrac{5}{7} = \dfrac{2}{7}$
Hence, $\dfrac{2}{7}$ fraction of orange is left in the basket after giving the $\dfrac{5}{7}$ fraction of total oranges in the basket to Javed.

Note: The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
