Express as metres using decimals:
(a) 15 cm
(b) 6 cm
(c) 2 m 45 cm
(d) 9 m 7 cm
(e) 419 cm
(a) We know that,
100 cm = 1 m
Therefore,
15 cm = m
= 0.15 m
(b) We know that,
100 cm = 1 m
Therefore,
6 cm = m
= 0.06 m
(c) We know that,
100 cm = 1 m
Therefore,
2 m 45 cm = (2 + ) m
= 2 + 0.45 m
= 2.45 m
(d) We know that,
100 cm = 1 m
Therefore,
9 m 7 cm = (9 + ) m
= 9 + 0.07 m
= 9.07 m
(e) We know that,
100 cm = 1 m
Therefore,
419 cm = m
= 4.19 m
