There are 144 people in an audience. The ratio of adults to children is 5 to 3. How many are adults?
PLEASE HELP!
Thanks, I didn't know how to set it up
5/8 = x/144
Cross multiply and solve for x.
You're welcome. :-)
ms sue how did u get 5/8
julie, if you add up 5 and 3 you get 8 so you get 5/8. then you do x/144. then solve for x with the full equation being 5/8 = x/144
To find the number of adults in the audience, we first need to determine the ratio between adults and children. Given that the ratio of adults to children is 5 to 3, we can calculate the proportion of adults in the audience.
Step 1: Calculate the total number of parts in the ratio.
The ratio has a total of 5 + 3 = 8 parts.
Step 2: Determine the value of one part.
To find the value of one part, divide the total number of people in the audience by the total number of parts in the ratio.
144 people / 8 parts = 18 people per part.
Step 3: Calculate the number of adults.
Multiply the value of one part by the number of parts representing adults.
18 people/part * 5 parts = 90 adults.
Therefore, there are 90 adults in the audience.
