Question

What is 50m as a fraction of 1km? Write the answer in the lowest terms.

Answer 1

$1km\to1,000m \\\\ p\% \ of 1,000m=50m \\\\ \frac{p}{100}*1,000m=50m \\\\ p*10m=50m \\\\ \boxed{p=\frac{50m}{10m}=5}$

Answer 2

There are 1,000 metres in a kilometre.

50m is 1/20 of a kilometre as 50 goes into 1,000 twenty times.
