(13) Katarina and Fran are helping their teacher divide consumable supplies for the workshop. The teacher gave them 17.80 liters of paint to divide evenly among 8 equal containers.

Katarina suggested each container should receive 42 liters, but Fran disagreed and said they should calculate it precisely using decimal division. (a) How many liters of paint goes into one container if 17.80 liters are distributed evenly? (b) Who was right, Katarina or Fran? Explain why. (c) How much paint would each container get if the paint were divided into 5 equal parts? (d) If one container accidentally got 0.20 liters more than it should have, how much paint is left for the remaining containers? (Assume the remaining paint is distributed evenly among the original remaining containers.)
