Question

Convent
15 cm into km.​

Answer 1

Answer:

0.00015 km

Step-by-step explanation:

$1cm = \frac{1}{100} m = \frac{1}{100} \times \frac{1}{1000} km = \frac{1}{100000} km$

$15cm = \frac{15}{100000} km = 0.00015km$

Answer 2

Answer:

1cm = 1/100m

so,

15 cm = 15×1/100 m

=15/100m

1m = 1/1000km

so,

15/100m = (15/100)×(1/1000)

=15/1000000km=1.5×10⁵km

Therefore,

15cm=1.5×10⁵km
