Teddy uses 2.5 gallons of ice to fill 4 buckets. He needs to 30 buckets. how many gallons of ice will teddy need

18 3/4 gallons of ice.

Step-by-step explanation:

By proportion we have:

4/2.5 = 30/x where x is the number of gallons of ice.

4x = 30*2.5

4x = 75

x = 18 3/4.

18.75 gallons of ice

Step-by-step explanation:

I divided the 2.5 gallons of ice by the number of buckets (4) it filled to determine how many gallons of ice are in each bucket.

2.5 / 4 = 0.625

I then multiplied the amount of ice it takes to fill a bucket (0.625) by 30 buckets to get 18.75 gallons of ice.
