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?

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.

how does your understanding of the multiplicative inverse help you determine the unit rate for complex fractions?

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