A school goes through 10 gallons of milk in 3 days.
Li wants to know how many gallons they use in 1 day. Emma wants to know how long 1 gallon will last.
110 × 3
3 × 110
10 ÷ 3
3 ÷ 10
110 of 3
Li: How many gallons in 1 day?
Emma: How many days does it take to finish 1 gallon?
Other:
g = gallons d = days 10g = 3d ?g = 1d 1g = ?d ------------- for gallons in a day, divide 10g = 3d by 3 d = 10/3 gallons 3 and 1/3 gallons in a day --------------- for days per gallon, divide 10g = 3d by 10 g = 3/10 days 1 gallon lasts 3/10 of a day
