Question
The value of 4 ÷ .
- 12
- 16
- 8
- 4
Hint:
The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
The correct answer is: 16
Here, we have to divide 4 by ¼.
We have, 4 ÷ ¼
= 4×4
=16.
Hence, the correct option is B.
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.

In the question, another approach could be that we first reduce the second fraction in its simplest form which is 1 ( because any number by the same number is always 1).
Now the expression becomes which is equal to as any number multiplies by 1 is always the number itself.
Thus, option (a) is the correct option.
