Question

Write a real world problem that can be represented by the equation 3/4c=21

Answer 1

There are 21 books in a table if the number of books is 3/4th of the cost of each book then what is the cost of each book.

Solution :

Let c represents the cost of each book,

Also, the number of books = 21

According to the question,

3/4th of the cost of each book = total number of books

`\implies (3)/(4)c = 21`

Which is the required equation.

Answer 2

Answer: Real world problem is "A student have c toffee he distribute
`(3)/(4)`th part of those toffees to his friends. He gave total 21 toffees to his friend".

Step-by-step explanation:

Let a student have c number of toffees in his bag.

It is given that he distribute
`(3)/(4)`th part of those toffees to his friends.

The
`(3)/(4)`th part of c toffees is,

`(3c)/(4)`

The total number of distributed toffees is 21.

`(3c)/(4)=21`

It is the same as given equation.

If we change the equation in words it means the
`(3)/(4)`th part of a number c is 21.
