In a recent year, there were approximately 140 moviegoers in a certain country. Of these, about 7/20 were ages 16-23. Find the approximate number of people ages 16-23 who attended the movies in that year.

49 people ages 16-23 who attended the movies in that year.

Step-by-step explanation:

The proportion of movie goers who were ages 16-23 is 7/20.

There were approximately 140 moviegoers in this country.

To find the approximate number of people ages 16-23 who attended the movies in that year.

We multiply the proportion by the approximate number of moviegoers.

Therefore 49 people ages 16-23 who attended the movies in that year

step-by-step explanation:

divided 3/4 and 6

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
