We will learn the use of decimal in measuring the length.
As we already know that,
100 centimetres = 1 metre or 100 cm = 1 m
So, 1 cm is one hundredths of a metre.
or, 1 cm = \(\frac{1}{100}\) m = 0.01 m
Similarly, 40 cm = 0.40 m (40 centimetres is forty hundredths of a metre)
25 cm = 0.25 m (25 centimetres is twenty five hundredths of a metre)
Metres and centimetres can be expressed together as
decimals.
For example,
8 m 40 cm = 8.40 m
19 m 1 cm = 19.01 cm
24 m 5 cm = 24.05 cm
25 m 58 cm = 25.58 m
51 m 11 cm = 51.11 cm
98 m 36 cm = 98.36 cm
