The ratio of oranges to people in the fruit salad is 9/40 if Lisa wants to serve 800 people how many oranges will Lisa use
oranges/800 = 9/40 = 180/800
The answer is 180/800
To find out how many oranges Lisa will use to serve 800 people, we need to determine the ratio of oranges to people and then calculate.
Given that the ratio of oranges to people in the fruit salad is 9/40, we can set up a proportion to solve for the number of oranges.
The proportion can be set up as follows:
Oranges/People = 9/40
To find the number of oranges, we can cross-multiply:
Oranges = (9/40) * People
Now, substitute the value of the number of people, which is 800 in this case:
Oranges = (9/40) * 800
To simplify this calculation, divide 800 by 40:
Oranges = (9/1) * 20
Next, multiply 9 by 20:
Oranges = 180
Therefore, Lisa will use 180 oranges to serve 800 people.
