To find out the fraction of packages on which the company lost money, we need to calculate the total number of packages returned with more than 3/4 of the pictures.
Total packages returned with more than 3/4 of the pictures = 7/8 + 7/8 + 5/8 + 5/8 + 3/4 + 3/4 = 6
Total number of packages returned = 3 + 3 + 2 + 2 + 4 + 4 + 2 = 20
Fraction of packages on which the company lost money = 6/20 = 3/10
Therefore, the company lost money on 3/10 or 30% of the packages returned.
A school photography company allows parents to purchase fractions of portrait packages. Parents can select only the pictures they want, and return a fraction of package. The company tracks the fraction of each returned package. The company loses money on any package returned with more than 3/4 of the pictures. On what fraction of the packages did the company lose money?
Portrait Packages Returned
1/8 - 3
1/4 - 3
3/8 -2
1/2 - 2
5/8 - 4
