### How I stopped an Alien Invasion using Proportion

First Problem.

A. Make a fraction table, at the left side put a 60 km over the line and put 3 hrs under the line.at right side put 120 km over the line and put 6 hrs under the line.which makes 60 x 2=120 and 3 x 2=6.120km for 6 hrs............................................................................................................................. B. Make a fraction table, at the left side put \$3 over the line and put 4 cans under the line. at the right side put \$15 over the line and put 20 cans under the line.which makes 3 x 5=15 and 4 x 5=20.\$15 for 20 cans.............................................................................................................................. C. Make a fraction table, at the left side put 178 beats over the line and put 2 mins. under the line. at the right side put 89 beats over the line and put 1 min. under the line.which makes 178/2=89 and 2/2=1................................................................................................................................. D. Make a fraction table, at the left side put 48km over the line and put \$16. under the line. at the right side put 192km over the line and put \$64. under the line.which makes 48 x 4=192 and 16 x 4=64.

Second Problem.

a) Make a ratio table, to get the unit rate you need to find three things. \$7.50, 3 rides, 1 ride.

Divide 7.50 to 3 to get the cost of how much per ride.

b) After you find the unit rate. Multiply the unit rite to find how much 18 rides cost.

Third Problem.

A) Make a ratio table to find how much 6kg of pickerel cost. Multiply the price of 2kg in to 3 so 17.60 x 3 = 52.8.

B) Make another ratio table, and turn 2kg into 2000g and divide it into 20.
To get 1600g get 100g and multiply it to 16.

The Aliens are taking over......

An alien has landed on earth from another planet.He is a scout for his planet. After a few minutes
a some kind of creature come out on a UFO. It want to know what is a proportion is or it will take offer the the earth. A proportion is a relationship that say that two ratios or two rates are equal. Proportion can be written in to fraction form. There is 2 different ways to show proportion
1 is using a ratio table and the other 1 is using fraction.
