Decimal Arithmetic

Division

I. Division by a Whole Number

• Ignore the decimal point; use Long Division as with whole numbers

• Put the decimal point upon the answer above in the same spot as the dividend (number being divided)

Exercise 4.

Perform the following division without using a calculator, rounding to 3 decimal places:

II. Division by a Decimal Number

• Convert the divisor to a whole number first (by multiplying both numbers by 10, 100, etc.) then continue as in I. Division by a Whole Number
  

Example 4A.

The result from 1.26 ÷ 0.7 is the same as that from 12.6 ÷ 7. Thus

Hence 1.26 ÷ 0.7 = 1.8
