Question

Convert the following into numerical scale (R.F):
2cm to 1km

Answer 1

Answer:

2cm:1km

1km=1000cm

2cm:1000cm

2/1000=1/500

Answer 2

Answer:

2/100000 km or 2 × 10^-5 km

Explanation:

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

therefore ,

$1 \: cm \: = \frac{1}{10000} km$

Then

$2 \: cm \: = \frac{2}{100000} \: km \: = \frac{2}{ {10}^{5} } = 2 \times {10}^{ - 5} km$
