Express as cm using decimals:

(a) 5 mm

(b) 60 mm

(c) 164 mm

(d) 9 cm 8 mm

(e) 93 mm

(a) We know that,

10 mm = 1 cm

Therefore,

5 mm = cm

= 0.5 cm

(b) We know that,

10 mm = 1 cm

Therefore,

60 mm = cm

= 6 cm

(c) We know that,

10 mm = 1 cm

Therefore,

164 mm = cm

= 16.4 cm

(d) We know that,

10 mm = 1 cm

Therefore,

9 cm 8 mm = (9 + ) cm

= 9 + 0.8 cm

= 9.8 cm

(e) We know that,

10 mm = 1 cm

Therefore,

93 mm = cm

= 9.3 cm
