The power of proportion!

I was walking to school, when I saw a UFO land on my school. I ran inside and saw that the aliens were holding Mr.Harbeck hostage, then he yelled. "Noel, save me with your proportion skills." Then I replied, "Don't worry Mr.Harbeck, Noel is here!" So then i grabbed a text book and yelled out the following question:

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.

This is what I did:
I got to the unit rate per hour, that looked like this:
5h/5=1h
$35/5=$7

So then I got $7/hour.

I then had to get the $ for 3 hours:
1h x 3 = 3hours
$7 x 3 = $21

I saw that one of the tenticles that were holding Harbeck got loose, and it only had 2 tenticles left. So I hit him with another question:

David can saw a log into three pieces in 7 minutes. If he continues sawing at a constant rate, how long will it take him to saw a similar log into 6 pieces?

This is my answers:
To get from 3 pieces to 6 pieces you would have to double it, so I just doubled 7 minutes to get 14 minutes.

Then I noticed a liquid falling onto Harbeck's head, it was the aliens eyeballs. They melted so I decided to give another question a shot and it would die. Here was the last question:

Two quarters has the same value as ten nickels.

What is the values of five quarters in nickels?

Here's what I did:
I used a unit rate to find the answer to this question.

2 quarters / 2 = 1 quarter
10 nickels / 2 = 5 nickels

then I followed up with this;

1 x 5 = 5 quarters
5 x 5 = 25 nickels

Once I finished that sentence the alien exploded and the room was covered in green goo. Harbeck then thanked me and pressed on the intercom; "Office, Can you get Moses down here to clean this up."

THE END!

How to stop an Alien Invasion using Porportions

One clear silent morning, something came from the sky. It was shaped as an oval, it was so many dazzling lights, it was a UFO! While it was coming down, it sent messages on the t.v that they'll take over the Earth. As the aliens continued to talk they said that they'll go away if someone answers three proportional questions that was waiting at three convenience store. I took that chance to saved the earth and went to the nearest convenience store.

The first convenience store question was:
Question- 6.Delia was paid $35 for 5h of babysitting. How much should should she receive for 3h? Use a unit rate to find the answer.
Answer-
She received $21 in 3 hrs.
I successfully got the question right and I was down to 2 more. I headed down to the next convenience store, knowing that my next question will be waiting for me.
Question- 13.Two quarters have the same value as ten nickles. What is the value of five quarters in nickles?
Answer-

The value of 5 quarters in nickles is 25 nickles.

I got the question right and I was left with 1 question left I went to the last convenience store in my neighbourhood. The last question was waiting for me.
Question- 17. Fresh pickerel is advertised in a local market.
a.) How much will 6kg of pickerel cost?
b.) Use a proportion to find the cost of 1600g of pickerel.
Answer-
a.)


The cost of 6kg of pickerel is $52.80.
b.)

The cost of 16kg of pickerel is $14.08.

I was done all my questions! I went out of the convenience store seeing an alien waiting for me. He told me I did a great job and said that they will leave the planet without harming it. I headed home seeing the UFO leaving. I woke up and realized it was all a dream. ;)
