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.
