Amodel rocket is built to scale is 3 cm = 5 m. if the model is 9.4 cm tall, how tall is the actual rocket?

Since there may be an easier way, you can find how many centimeters there may be for one meter by dividing both sides (3 cm = 5 m ) by 5.

So, .6 cm= 1 m
This will make it easy to divide to find the actual ticket size.
You have to find how many .6 there are in 9.4 by dividing:

The rocket would be

m tall.
