### How I Stoped an Alien,Bruce8-16(late)

It was an ordinary day all the sudden a UFO landed and threatened to take over the Earth. Unless I answer 3 of it's proportional questions correctly the alien will take over the world.

The first question was:
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?
In the same amount of time that the small gear turns 54 times, the large gear would have turned 12 times.The alien said it was right but not to be too happy because it was probably just luck the answer was right.

The second question is:
Look at the pattern, set up a proportion you could use to find the number of small squares in Figure 7.
In figure 7, there would be 14 squares. The alien is getting nervous which means I was correct and all I needed was one more question to go.

The third and last question:

The dosage of a certain medicine for a child is 2.5 ml for each 3 kg mass of the child. What is the dose, in millilitres, for a child with a mass of 16.5 kg?
For a child with a mass of 16.5 kg, they will have a dose of 13.75 ml of the medicine. I got all three questions right which meant I had defeated the alien. The alien left and I had saved the earth!

Sorry about not having any pictures, my computer wasn't working right.

1. Good job, well explained.

2. Aha Good Job Bruce! The answers are correct. But you didn't explain or show how you got the answer. Next time you should do that! By the way, nice story! :]

3. i agree with jennifer that your answers are right....it would be better if you showed or explained how you got your answers

4. Jood job Bruce! :)
