E. A tank had 1 kL water. From this tank, 3 drums of capacities 150 L, 200
L and 225 L were filled. How much water was left in the tank?
F. Vashu, Megha and Krish, having respective weights 34 kg 5 hg, 32 kg 4 hg and
36 kg 5 hg went for a ride in the amusement park. There was a restriction

which two cannot go on that ride together?
Multiplication and Division of Metric Measures
We can multiply or divide metric measures like whole numbers using place
value or like decimals by converting it into a single unit.
Example 6: Multiply 1 kg 3 hg 5 dag 7 g by 4 using place value.
Solution: Arrange the numbers properly and multiply.
kg hg dag g
1 3 5 7
× 4
5 4 2 8
Express the result in the given units.
Thus, 1 kg 3 hg 5 dag 7 g × 4 = 5 kg 4 hg 2 dag 8 g
Example 7: Multiply 3 L 6 dL 3 cL 4 mL by 12 and express your result
in litres.
Solution: As 3 L 6 dL 3 cL 4 mL = 3.634 L
So multiply 3.634 × 12
3 . 6 3 4
× 1 2
7 2 6 8
3 6 3 4
4 3 . 6 0 8
Thus, 3.634 L × 12 = 43.608 L
