Question

Sondra wants to gift box of cookies she made this weekend so that 1/3 of a batch of cookies goes into each box if she made 2 1/2 batches of cookies how many gift boxes will she have

Answer 1

We have to divide 2 1/2 by 1/3. To do this, first, we need to convert the mixed number into a fraction, as follows:

`2(1)/(2)=(2\cdot2+1)/(2)=(5)/(2)`

Dividing by a fraction is equivalent to multiplying by its inverse, then 5/2 divided by 1/3 is the same as 5/2 multiplied by 3.

`(2(1)/(2))/((1)/(3))=((5)/(2))/((1)/(3))=(5)/(2)\cdot3=(15)/(2)=7(1)/(2)`

She will have 7 gift boxes and some cookies leftover
