DAV Class 5 Maths Chapter 7 Worksheet 9 Notes
Division of a Decimal Number by another Decimal Number
Example.
Divide 1.6 by 0.2
Solution:
Here dividend = 1.6, divisor = 0.2
1.6 ÷ 0.2 = \(\frac{1.6}{0.2}\)
(Division expressed as a fraction)
Let us change the divisor into a whole number.
\(\frac{1.6}{0.2}=\frac{1.6 \times 10}{0.2 \times 10}\)
= \(\frac{16}{2}\)
= 8
0.2 has one decimal place so, multiply the numerator and denominator by 10 to get an equivalent fraction.
