The correct option is A 12
A fraction is said to be in the simplest form if its numerator and denominator are prime numbers, that is, they have no common factors other than 1 .
Here 24 = 12.
This comes as the result of dividing 24 from the highest common factor and in this case, it is 2. Since 2×2=4 we get the denominator of the simplest form as 2. Hence the answer 12.
24 = 12.
