Answer: Real world problem is "A student have c toffee he distribute [tex]\frac{3}{4}[/tex]th part of those toffees to his friends. He gave total 21 toffees to his friend".

Explanation:

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

It is given that he distribute [tex]\frac{3}{4}[/tex]th part of those toffees to his friends.

The [tex]\frac{3}{4}[/tex]th part of c toffees is,

[tex]\frac{3c}{4}[/tex]

The total number of distributed toffees is 21.

[tex]\frac{3c}{4}=21[/tex]

It is the same as given equation.

If we change the equation in words it means the [tex]\frac{3}{4}[/tex]th part of a number c is 21.

Answer:

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

[tex]\implies \frac{3}{4}c = 21[/tex]

Which is the required equation.
