Problem of the Week - Middle School - May 2, 2021 to May 8, 2021

Middle School: 

Question: The ratio of apples to oranges in a box is 7:18. What is the percent chance that a fruit drawn at random from the box will be an orange?

Answer: 72%

Solution: There are 7+18=25 fruits in the box. Since 18 out of 25 fruits are oranges and a percentage is out of 100, we can multiply 18 and 25 each by 4 to find the number of fruits out of 100 that are oranges. 18x4=72, so 72% of the fruits are oranges. If one is chosen at random, then the percent chance that it'll be an orange is 72%.
