Question

Convert 45 cm to dm ,m,hm and km

Answer 1

45 cm = 0.45 m because 100cm = 1m
45 cm = 4.5 dm because 1dc= 10cm
45 cm = 0.00045 km because 1km = 100000cm
45 cm = 0.0045 hm because 1 hm = 10000 cm

Answer 2

The values are 450 dm, 0.45 m, 0.0045 hm and 0.00045 km

GIVEN:- 45 cm

TO FIND:- Conversion to dm,m, hm and km

SOLUTION:-

As we know,

1dm = 10cm

45 cm = 45 × 10 = 450 dm

As we know,

100cm = 1m

45 cm = 1/100 × 45 = 0.45 m

As we know,

1 hm = 10000 cm

45 cm = 1/10000 × 45 = 0.0045 hm

As we know,

1km = 100000cm

45 cm = 1/100000 × 45 = 0.00045 km

Hence, the values are 450 dm, 0.45 m, 0.0045 hm and 0.00045 km
