How do you divide a whole number by a decimal?

Whole numbers are all natural numbers including zero. A decimal number can be defined as a number whose whole number part and the fractional part are separated by a decimal point.

Answer: To divide a whole number by a decimal number, multiply both the numbers with the power of 10 with the same number of zeros as the number of decimal places in the divisor. Then, divide them as we divide 2 whole numbers.

Let's look into an example to understand this.

Explanation:

For example, 4/0.2.

1. Remove the decimal from the denominator by multiplying both numbers by 10.
i.e, 40/2
2. Now divide numerator by denominator and get the answer.
i.e, 40÷2 = 20

Hence, to divide a whole number with a decimal number, convert the given decimal number into a whole number by multiplying with a power of 10, and then do the division.
