Question

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

Answer 1

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.
$3 \div 5 = .6 \\ 5 \div 5 = 1$
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:
$9.4 \div .6 = 15 \frac{2}{3}$
The rocket would be
$15 \frac{2}{3}$
m tall.
