A pie chart labeled Favorite Sports to Watch is divided into three portions. Football represents 42 percent, baseball represents 33 percent, and soccer represents 25 percent. If 210 people said football was their favorite sport to watch, how many people were surveyed?
42/100 = 210/x
Cross multiply
42x = 21000
Solve for x by dividing both sides by 42.
Thank you mrs.sue
Thanks Mrs.Sue
To find out how many people were surveyed, we can use the information given about the percentage of people who said football was their favorite sport to watch.
First, we know that 42% of the people surveyed chose football as their favorite sport to watch. We also know that this corresponds to 210 people.
To find the total number of people surveyed, we need to determine what 42% represents in terms of the whole.
Let's set up a proportion to solve for the total number of people surveyed:
42% (football) / 100% (whole) = 210 people / x (total number of people surveyed)
Cross-multiplying, we get:
(42/100) * x = 210
Simplifying the left side of the equation:
0.42x = 210
Now, we can solve for x by dividing both sides of the equation by 0.42:
x = 210 / 0.42
Evaluating the above expression:
x = 500
Therefore, the total number of people surveyed is 500.
