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

0.68L per dispenser

Step-by-step explanation:

Big bottle contain 213L of soap.

Big bottle will fill 312 dispensers.

This means 1 each dispenser can take 213/312 litres = 0.68L per dispenser.
