Answer:

a. 4.5 grams per cup

b. 3.2 ounces per week

c. 19.2 grams per cubic centimeters

d. $3.29 per gallon

Explanation:

The unit rate is simply a ratio comparing 2 given quantities, whereby the denominator is 1.

The unit rate of the above given problems can be determined as shown below:

a. 18 grams of salt per 4 cups, to find the unit rate, calculate how many grams of salt you'd get in 1 cup by dividing 18 by 4


(18)/(4) = 4.5

Unit rate = 4.5 grams per cup

b. 19.2 ounces is gained by the baby in 6 weeks.

Unit rate is the amount of ounces gained in 1 week

Unit rate =
(19.2)/(6) = 3.2

Unit rate = 3.2 ounces per week

c. Unit rate =
(76.8)/(4) = 19.2

Unit rate = 19.2 grams per cubic centimeters

d. Unit rate =
(23.03)/(7) = 3.23

Unit rate = $3.29 per gallon
