Hint: To find the value of 30% of 24, we have to express this in the mathematical form by changing ‘of’ to a multiplication symbol. Then, we have to convert 30% into its number form by dividing 30 by 100. Then, we have to simplify the result.

Complete step by step solution:
We have to find the value of 30% of 24. Let us first express this in the mathematical form by changing ‘of’ to a multiplication symbol.
30%×24
Now, we have to convert 30% into its number form. We know that a percentage is converted into its number form by dividing it by 100. Therefore, we have to divide 30 by 100.
30100×24
Now, we have to cancel a 0 from 100 in the denominator and 30 in the numerator.
3\cancel010\cancel0×24
We can write the result of the above simplification as
310×24
We have to cancel the common factor 2.
3\cancel105×\cancel2412
We can write the result of the above simplification as
35×12
Now, let us multiply 3 and 12.
365
Now, we have to divide 36 by 5.
7.2

Therefore, 30% of 24 is 7.2.

Note: Students must know how to convert a number into its percentage form and vise-versa. The former is done by multiplying the number 100 times. To simplify a result, we have to first cancel the zeroes in the unit place if both the numerator and denominator have one or more. Then, we have to further simplify by cancelling the common factors. If the result is in fractions, it is compulsory to convert the fraction into its decimal form.
