Express as meters using decimals.
`(a) 15 cm`
`(b) 6 cm           `
`(c) 2 m 45 cm`
`(d) 9 m 7 cm       `
`(e) 419 cm`

Explanation

We know, `100` cm = `1` m

So,

(i) `15` cm ` = 15/100 = 0.15` m

(ii) `6` cm ` = 6/100 = 0.06` m

(iii) `2` m `45` cm ` = (2+45/100) = 2.45` m

(iv) `9` m `7` cm ` = (9+7/100) = 9.07` m

(v) `419` cm ` = 419/100 = 4.19` m
