Subtraction with metres & centimetres

■ Note: we arrange m and cm in different columns and

subtract in the regular method.

■ Example: a) Subtract 125 m 80 cm from 387 m 56 cm

Step-1 Subtract cm column first

6 – 0 = 6 (write)

After borrowing from m: 15 – 8 = 7 (write)

Step-2 Then subtract m column

Left 6 – 5 = 1 (write)

8 - 2 = 6 (write)

3 - 1 = 2 (write)

Thus, 387 m 56 cm - 125 m 80 cm = 261 m 76 cm
