Tutor: None Selected  Time limit: 1 Day 
The Helvie family drinks 1 3/4 gallons of milk every 4 1/2 days. What it is the unit rate they drink per day.
The Helvie family is going on a seven day vacation.Mr Helvie stops by the grocery store and purchases 3 gallons of milk.Based on the number of gallons of the family drinks per day, will he have to purchase more milk during thier vacation?
how does your understanding of the multiplicative inverse help you determine the unit rate for complex fractions?
Thank you for the opportunity to help you with your question!
they take 1 3/4 galons within 4 1/2 days
in one day they take (1 3/4 )/ (4 1/2)
converting to mixed fraction gives
(7/4)/(9/2)
Multiply the first by the reciprocal of the second
(7/4 ) x (2/9)= 14/36
Simplifying gives
They consume 7/18 in a day

3 gallons
vacation is 7 days
it will need 7 x 7/18 gallon
= 49/18
= 2 11/18
Since its not greator than 3 gallons, they will not need more milk.

it helps me in division of complex fractions as well as in simplifying.
