Question

Express 10cm in meter and kilometer

Answer 1

1m=100cm
therefore 1 cm = 1/100
=0.001m
1km=1000m=100×1000cm
1km=100000cm
hence 10 cm=10/100000=0.0001km

Answer 2

Given:

10 cm

To express:

10 cm in meter and kilometer

Solution:

We know that

$1cm=\frac{1}{100} m$

$1 cm=\frac{1}{100000}km$

Using the formula

$10cm=\frac{1}{100}\times 10 m=0.1 m$

$10cm=\frac{1}{100000}\times 10=0.0001 km$

Hence,

10 cm=0.1m

And

10 cm=0.0001 km
