Sub-topic 7 : WORD PROBLEMS OF METRIC MEASUREMENTS:
Example:1- The height of building X is 6314 cm and that of building Y is
229 cm less. What is the height of building Y?
Solution:
The height of building X = 6314 cm = 63.14 m
The height of building Y is 229 cm less than building X.
Therefore, the height of building Y = 63.14 m - 2.29 m
Hence, the height of building Y = 60.85 m
The total length of 9 ropes of equal length is 19 m 20 cm. What is the
length of each rope?
Total length of 6 ropes = 19 m 20 cm
Length of each rope = 19 m 20 cm ÷ 6
Ans: 3 m 20 cm
Example:2- The length of a rope is 80 m. If a piece of 35 m 40 cm length
is cut, what length of the rope is left?
Solution:
Total length of the rope = 80 m 00 cm
Piece cut from the rope = - 35 m 40 cm
