Joan has 1/3 of a roll of wrapping paper. She wants to use it to wrap 5 presents for her dad's birthday party. How much wrapping paper will she use on each present if she uses equal amounts for each one?
To find out how much wrapping paper Joan will use on each present, we first need to determine the total amount of wrapping paper she has.
Since Joan has 1/3 of a roll of wrapping paper and she wants to wrap 5 presents with equal amounts, we need to divide the amount of wrapping paper by the number of presents:
1/3 ÷ 5 = 1/3 ÷ 5/1 = 1/3 x 1/5 = 1/15
So, Joan will use 1/15 of a roll of wrapping paper on each present.
