suBtraCtion of lengths

To subtract km, m and cm, follow the steps given below:

Step 1: Make two columns of m and cm and write the given lengths in appropriate columns
such that the smaller length is written below the bigger length.

Step 2: Subtract the lengths like ordinary numbers.

Example 1: Subtract the following.

(a) 27 cm from 55 cm (b) 16 m from 90 m.
Solution: (a) 4 15 (b) 8 10

5 5 cm 9 0 m
– 2 7 cm – 1 6 m

2 8 cm 7 4 m
