Express as cm using decimals.
`(a) 5 mm           `
`(b) 60 mm          `
`(c) 164 mm`
`(d) 9 cm 8 mm      `
`(e) 93 mm`

Explanation

We know, `10` mm = `1` cm

So,

(i) `5` mm` = 5/10 = 0.5` cm

(ii) `60` mm` = 60/10 = 6` cm

(iii) `164` mm` = 164/10 = 16.4` cm

(iv)`9` cm `8` mm` =(9+8/10) = 9.8` cm

(v) `93` mm` = 93/10 = 9.3` cm
