DAV Class 5 Maths Chapter 7 Worksheet 10 Notes
Division of a Whole Number by a Decimal Number
Example 1.
Divide 9 by 0.3
Solution:
9 ÷ 0.3
= \(\frac{1}{2}\) (Division expressed as a fraction)
= \(\frac{9 \times 10}{0.3 \times 10}\) (Divisor has one decimal place. So, multiply both numerator and denominator by 10)
= \(\frac{90}{3}\)
= 30
Example 2.
Divide 54 by 0.03
Solution:
54 ÷ 0.03
= \(\frac{54}{0.03}\)
= \(\frac{54 \times 100}{0.03 \times 100}\)
= \(\frac{5400}{3}\)
= 1800
