a model of a park was built on a scale of 1.5 centimeters to 50 meters.If the distance between two trees in the park is 150 meters,what is this distance on the model?

miranda enlarged a picture propotionally.Her original picture is 4 cm wide and 6 cm long.If the new,larger picture is 10 cm wide, what is its length?

You should be able to do this in your head.
Isn't the 150m three times the 50 m of the scale?
so what is 3 x 1.5 ?
or solve
x/1.5 = 100/50 
What did Miranda multiply the 4 cm by to get 10 cm?
Do the same thing to the 6 cm. 
4.5

how long is a rectangular if its 15 inches wide
