Determine how many times the distance is reduced on plans built on a scale: 1:50, 1: 100, 1: 150, 1: 5000?

The scaling system in modern cartography is built on the principle of reducing the original. The designation system is as follows:
On the left, the number 1 – expresses the fact that one centimeter is considered a conventional unit on the map.
To the right of the colon is a number that indicates how many centimeters in real areas fit into one centimeter.
1:50 in 1 centimeter on the map 50 cm in reality. Reduced by 50 times.
1: 100. Reduced by 100 times.
1: 150. Reduced by 150 times.
1: 1000. 1 cm 10 meters. Reduced by 1000 times.
