How I stopped an Alien Invasion with proportion :D

It was a beautiful summer night , a full moon plus many stars . I decided to go lay down on the deck and watch the stars , hoping for a shooting star ! I was very quiet , until i heard something flying high up above my head ! I looked up to see a large object of some sort, it was extremely fast . I closed my eyes , and made a wish .. * CRASH !* i ran out to whatever it was . It wasn't a shooting star , because there were lights on it . to my surprise , out popped a small weird looking creature . "Hello , I come in peace " . I saw it in movies , so i thought it would world . Apparently , they didn't like when i did that , the small creature then pulled out a ray of some sort . While pointing it at me , he said " Answer three of our questions . If you do not answer them correct , we destroy your planet . If you answer them correctly , we shall know you humans come in peace and we will leave to our planet ."

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.

In the same amount of time that the small gear turns 54 times, the large gear would have turned 12 times.

At an amusement park, a new thrill ride was introduced. It costs $7.50 for 3 rides on the Wild Slider.

a) What is the Wild Slider’s unit rate per ride?

rides / $

3/7.50

3/3=1

7.50/3=2.50

so .. it is $2.50/ per ride :)

b) At this rate, what would it cost for 18 rides on Wild Slider?Determine the answer two different ways.

rides/$

1/2.50

1 x 18 = 18

2.50 x 18=45

so .. 45 DOLLARS FOR 18 RIDES ;)

"Very good , I guess you humans aren't so bad like how they say you are . Thank you Earthling , Good bye ! "

Another space craft came , and picked up the small creature .

" Goodbye ! (: "
