Final answer:
By dividing 23 by 18, it's determined that the artist could fill 1 container completely with 5 gallons of paint left over.
Step-by-step explanation:
The question relates to basic division. If an artist had 23 gallons of paint and poured 18 gallons into each container, to find out how many containers he filled, you need to divide the total paint by the amount put into each container:
- Divide 23 gallons by 18 gallons per container to get the number of containers filled: 23 / 18 = 1 remainder 5.
- This means that 1 full container was used, with 5 gallons of paint left over.
23 gallons of paint into the containers, only 1 container would be filled completely with 5 gallons remaining.
