We know that, 1000 m = 1 km
40
So, 40 m = km = 0.04 km
1000

Money

We know that, 100 paise = ` 1
1
So, 1 paise = ` or ` 0.01
100
65
and 65 paise = ` = ` 0.65
100

105
Similarly, 105 paise = ` = ` 1.05
100

Weight
We know that, 1000 g = 1 kg
1
1 g = kg
1000
50
50 g = kg = 0.050 kg or 0.05 kg
1000
500
500 g = kg = 0.5 kg
1000

2350
Similarly, 2350 g = kg = 2.350 kg or 2.35 kg
1000
