Incorrect question

Corrected question:

Noah fills a soap dispenser from a big bottle that contains 2 1/3 liters of liquid soap. That amount of soap will fill 3 1/2 dispensers. How many liters of soap fit into one dispenser?

Step-by-step explanation:

Total volume of soap in the dispenser = 2 1/3 liters

Converting to improper fraction = 7/3 liters

Total number of dispenser the soap can fill = 3 1/2

Converting to improper fraction = 7/2

How many liters L of soap fit into one dispenser;

L = number of liters per dispenser

L = Volume of soap/number of dispensers

L = 7/3 ÷ 7/2

L = 7/3 × 2/7 = 2/3 liters per dispenser

L = 2/3 or 0.67 liters per dispenser
