  • Writing Small Numbers
  • End of Lesson Evaluation Questions

Small numbers are numbers less than zero and are called decimal fractions.

e.g.  0.000 065,  0.004 etc.

To write small numbers, group them in three from the decimal point to the right.

e.g. 0.000000125 can be written as  0.000 000 125  

Worked Example 6.4.1:

Write these as decimal fractions and group the digits in three where necessary.

a. 10 millionth 
b. 25 hundredth
c. 68 × 10-7
d. \( \frac{150}{1000000} \)

Solution

a. 10 millionth = \( \frac{10}{1,000,000}\\ = \scriptsize 0.00001\)
