Subtraction of Metric Measures

We will discuss here about the subtraction of metric measures. Metric measures are subtracted in the same way as we subtract ordinary numbers. We arrange the digits in columns and then subtract as required.

Let us consider an example.

1. Subtract 6 kg 7 g 2 dg 5 mg from 12 kg 5 dag 8 g 9 mg.

We place the digits in columns and then subtract as usual.

Ans. 6 kg 5 dag 8 dg 4 mg

Word problems on subtraction of metric measures:

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

Remaining rope                            =            44 m 60 cm

Hence, the length of the rope left = 44 m 60 cm.
