DAV Class 5 Maths Chapter 7 Worksheet 12 Notes
A decimal number divided by one is the decimal number itself.
Example:
(a). 8.9 ÷ 1 = 8.9
(b) 0.036 ÷ 1 = 0.036
Zero divided by any decimal number is zero.
0 ÷ 4.6 = \(\frac{0}{4.6}\)
= \(\frac{0 \times 10}{4.6 \times 10}\)
= \(\frac{0}{46}\)
= 0
A decimal number divided by itself is one
Example:
0.2 ÷ 0.2 = \(\frac{0.2}{0.2}\)
= \(\frac{0.2 \times 10}{0.2 \times 10}\)
= 1
0 ÷ 0.07 = \(\frac{0}{0.07}\)
= \(\frac{0 \times 100}{0.07 \times 100}\)
= \(\frac{0}{7}\)
= 0
