Question

As a fundraiser, the Music Boosters wrapped gifts at the mall one weekend. Out of the 100 gifts they wrapped, 3/10 were for weddings, and 37/100 were for baby showers. The rest of the gifts were for birthdays. What fraction of the gifts was for birthdays? Enter your answer in the boxes.

Answer 1

Answer: The fraction of the gifts were for birthdays =
`(33)/(100)`.

Explanation:

Given: fraction of gifts for weddings =
`(3)/(10)`

fraction of gifts for baby showers =
`(37)/(100)`

Rest of the gifts =
`1-\frac3{10}-(37)/(100)`

`=(100-30-37)/(100)\ \ \ [\text{Making like fractions}]\\\\=(100-67)/(100)\\\\=(33)/(100)`

Hence, the fraction of the gifts were for birthdays =
`(33)/(100)`.
