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
