**Point shift trick**

Division: Point is shifted to the left by the number of zeroes in the denominator.

- (Shifting decimal by 2 points to the left)
- (Shifting decimal by 3 points to the left)

__Decimals in length measurement__

- 1 m = 100cm
- 1cm = m = 0.01 m (Move decimal to left by 2 units in the numerator as there are two zeroes in the denominator)
- 150cm = m = 1.5 m

__Decimals in weight measurement__

- 1 kg = 1000 g
- 1 g = kg
- 298 g = kg = 0.298 kg (Move the decimal to the left by 3 places in the numerator as there are 3 zeroes in the denominator)
