3 gallons of batter are poured equally into 4 bowls. How many gallons of batter are in each bowl?
Usimov [2.4K]

Answer:

0.75 gallon

Step-by-step explanation:

3 gallons of batter are poured equally into 4 bowls.

We have to calculate the amount of batter in each bowl.

so we have to divide 3 gallons by 4 to get the answer.

Total amount of batter = 3 gallons

divided into number of bowls = 4

The amount in each bowl =  \frac{3}{4}  gallons

                                          = 0.75 gallons

0.75 gallon of batter are in each bowl.
