### How I Stopped an Alien Invasion Using Proportion Jerick873

These are the questions I chose.

#19 pg 68

Determine the missing value in each equivelent fraction.

3=18=x9

x4=24=12

To solve this, use the information that was already given so to get to 3 using 18 divide by 6 so what you do to one side you do to the other , and to get to 9 from 18 divide by 2

#18 pg 68

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

a) $/# of rides

7.50/3

2.50/1To figure the unit rate you have yo make the # of rides 1 so divide by 3 and what you do to one side you do to the other.

b) $/#of rides

2.50/1

45/8

$45/18 ride

$ = 7.50 = 45

#of rides = 3= 18

To do this, since you know the unit rate you multiply that by 18 and you do the same to the other side and you get your answer.

#10 pg 67

Set up a proportion for each situation

a) # of beans = 10 beans = 30 beans

mass = 17 g = 51 g

To set up a proportion all you do is put it like that or in a table
