A painter uses 2.75 gallons of paint per hour. How many gallons of paint will the painter use in 3.5 hours?

you can set this us as a ratio problem:

2.75 gallons/1 hr = x/3.5 hrs

x = 2.75 x 3.5

x = 9.625 gallons

Or you know 2.75 gallons in 1 hour so you would just multiply 3.5 hrs

9.625 gallons will be used by the painters in 3.5 hours

Step-by-step explanation:

2.75 gallons = 1 hr

X gallons = 3.5 hrs

X = (3.5 * 2.75) / 1

X = 9.625 gallons

9.625 gallons will be used by the painters in 3.5 hours
