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?
it 500 people
this does not help
To find the total number of people surveyed, we can use proportional reasoning.
Since 42 percent of the people said football was their favorite sport to watch, and this represents 210 people, we can set up the following proportion:
42/100 = 210/x
To solve for x, we can cross-multiply:
42x = 210 * 100
42x = 21000
Divide both sides of the equation by 42:
x = 21000/42
x = 500
So, there were 500 people surveyed.
42/100 = 210/x
Cross multiply and solve for x.
