1.53 m = . . . cm

• 1 m = 100 cm

  So, 1.53 x 100 = 153

• 1 m = 100 cm

  So, 1.53 x 100 = 15.3

• 1 m = 100 cm

  So, 1.53 x 100 = 1.53

12.03 m = . . . m . . . cm

(Hint. 1m = 100 cm)

• 12.03 m= 12 m + 0.03 m

  0.03m= 0.03 x 100 = 3 cm.

  So, 12.03m = 12m 3cm

• 12.03 m= 12 m + 0.03 m

  0.03m= 0.03 x 1000 = 3 cm.

  So, 12.03m = 12m 3cm

• 12.03 m= 12 m + 0.03 m

  0.03m= 0.03 x 100 = 30 cm.

  So, 12.03m = 12m 30 cm

Multiple Choice

217.9 km = . . . km . . . m

(Hint. 1 km = 1000 m)

• 217.9 km = 217 km+ 0.9 km

  0.9km= 0.9 x 1000 = 900m.

  So, 217.9km = 217km 900m

• 217.9 km = 217 km+ 0.09 km

  0.09km= 0.09 x 1000 = 90m

  So, 217.9km = 217km 90m

• 217.9 km = 217 km+ 9 km

  9km= 9 x 1000 = 9000m.

  So, 217.9km = 217km 9000m

3.64 kg = . . . kg . . . g

(Hint. 1 kg = 1000 g)

• 3.64 kg = 3 kg+ 0.64 kg

  0.64 kg= 0.64 x 1000 = 64000

  So, 3.64 kg = 3 kg 64000 g

• 3.64 kg = 3 kg+ 0.64 kg

  0.64 kg= 0.64 x 1000 = 640

  So, 3.64 kg = 3 kg 640 g

• 3.64 kg = 3 kg+ 0.64 kg

  0.64 kg= 0.64 x 1000 = 6400

  So, 3.64 kg = 3 kg 6400 g

21 m 7 cm = . . . m

(Hint. 1 m = 100 cm)

• 7 cm = 7 : 100

  = 0.07 m

  So, 21 m + 0.07 m = 21.07m

• 7 cm = 7 : 100

  = 0.7 m

  So, 21 m + 0.07 m = 21.7m

• 7 cm = 7 : 100

  = 0.07 m

  So, 21 m + 0.07 m = 21.70m

42 km 6 m = . . . km

(Hint. 1 km = 1000 m)

• 6 m = 6 : 1000

  = 0.06 km

  So, 42 km + 0.06 km = 42.06 km

• 6 m = 6 : 1000

  = 0.6 km

  So, 42 km + 0.6 km = 42.6 km

• 6 m = 6 : 1000
