# Express as cm using decimals

(a) 5 mm

(b) 60 mm

(c) 164 mm

(d) 9 cm 8 mm

(e) 93 mm

**Solution:**

We know that 1 cm = 10 mm. To convert the mm into cm, we will divide by 10 and express it as decimals.

a) 5 mm

5 / 10 = 0.5 cm

b) 60 mm

60 / 10 = 6 cm

c) 164 mm

164/ 10 = 16. 4 cm

d) 9 cm 8 mm

(9 × 10 + 8) / 10 = 98 / 10 = 9.8 cm

e) 93 mm

93 / 10 = 9.3 cm
