### How I stopped an Alien Invasion using Proportion

I saw an ALIEN walking alone... I talked to him, and he ask me to do a favour.. that favour was to do 3 question from the text book.

Question # 8.

Determine the missing value.

a.) 2 10 b.) 2 14 c.) 30 6 d.) 3 12

-- = -- -- = -- -- = -- -- = --

3 15 5 35 45 9 4 36

Question # 16.

A gardener take a half hour to mow and weed a lawn that measures 20m by 15m, He charges $25 per hour. How much should the gardener receive for a lawn that measures 40m by 30m?

- 20m by 15m is $25 per hour.

- 40m by 30m would cost $50, Because 20 x 2 = 40 and 15 x 2 = 30.

- The cost of 40m by 30m will be $50

Question # 21.

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

minutes / pieces

7 minutes/3 = 3.5 3/3 = 1

3.5 x 6 = 14min 1 x 6 = 6

- It will take David 14 minutes, to saw six pieces of log.
