Multiplication of Measurements

To multiply the given measurements, follow these steps:

Step 1: Convert the measurement into the smaller unit.

Step 2: Multiply as the multiplication of whole numbers.

Step 3: Express the result into the given units.

Example 9: Multiply:

(a) 4 m 16 cm by 8 (b) 16 kg 135 g by 6

Solution: (a) 4 m 16 cm = 4 × 100 cm + 16 cm = 416 cm

× 8

3 3 2 8 cm = 3300 cm + 28 cm = 33 m 28 cm

Thus, 4 m 16 cm × 8 = 33 m 28 cm

(b) 16 kg 135 g = 16 × 1000 g + 135 g = 16135 g

Thus, 16 kg 135 g × 6 = 96 kg 810 g

Division of Measurements
