How I stopped an Alien Invasion using Proportions

The first term in Sargent park school is finally over, and the second term stress is yet to happen. But of course the report card stress isn't all the have to deal with. An alien scout has landed and if his computer isn't destroyed with 3 proportion questions answered correctly, the world as we know it is doomed to a fatal existence.

6.Delia was paid $35 for 5 h of babysitting. How much should she receive for 3 h? Use a unit rate to find the answer.

Delia would receive 21 dollars for 3 hours of babysitting.
11.A small gear turns 18 times in the same time that a large gear turns 4 times. How many times will the large gear turn if the small gear turns 54 times? Draw a diagram to help set up a proportion and solve the problem.

The big gear will have turned 12 times if the small gear turns 54 times.14. Last night 30 cm of snow fell in 6 h. If it continues snowing at the same rate, how long will it take for 45 cm of snow to fall?Determine the answer two different ways.

If it continued snowing at the same rate it would take 9 hours for the snow to reach 45 cm.
Now that there are three correctly answered portion questions entered into the aliens computer it self-destructs and the alien is left defenseless and flees back to it;s home planet never to return again.
