These are the questions I chose.
#19 pg 68
Determine the missing value in each equivelent fraction.
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
To 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
$ = 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.
