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
