Division of a Decimal by a 1-digit Decimal
Division of a decimal by a decimal is similar to whole number division.
Rules for Decimal Division
- First we make both the decimals have the same number of decimal places if required.
- Then we divide them as if they were whole numbers ignoring the decimal points.
- The quotient so obtained is the required answer.
Consider the following examples of division of a decimal by a 1-digit decimal
Divide 101.6 ÷ 0.8
101.6 has one decimal place. 0.8 has one decimal place. Here we move the decimal point to the right one place in both the numbers.
Now 101.6 ÷ 0.8 = 1016 ÷ 8 = 127
Divide 78.3 ÷ 0.9
Both 78.3 and 0.9 have one decimal place. Here we move the decimal point to the right one place in both the numbers.
Now 78.3 ÷ 0.9 = 783 ÷ 9 = 87
