Answer 1

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

Step-by-step 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

$\frac{18}{4} = 4.5$

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 = $\frac{19.2}{6} = 3.2$

Unit rate = 3.2 ounces per week

c. Unit rate = $\frac{76.8}{4} = 19.2$

Unit rate = 19.2 grams per cubic centimeters

d. Unit rate = $\frac{23.03}{7} = 3.23$

Unit rate = $3.29 per gallon
