<p>(13) §§Fm4§§ and §§M5§§ are helping their teacher divide consumable supplies for the workshop. The teacher gave them §§V4(10,20,0.2)§§ liters of paint to divide evenly among §§V5(6,12,2)§§ equal containers.</p>
<table class='table table-sm'>
<tr>
<td class="align-top" style="width: 66%">
<p>§§Fm4§§ suggested each container should receive §§V60(2,4,2)§§ liters, but §§M5§§ disagreed and said they should calculate it precisely using decimal division.</p>
<p>(a) How many liters of paint goes into one container if §§V4(10,20,0.2)§§ liters are distributed evenly?</p>
<p>(b) Who was right, §§Fm4§§ or §§M5§§? Explain why.</p>
<p>(c) How much paint would each container get if the paint were divided into §§V6(2,10,1)§§ equal parts?</p>
<p>(d) If one container accidentally got §§V61(0.1,0.3,0.1)§§ liters more than it should have, how much paint is left for the remaining containers? <i>(Assume the remaining paint is distributed evenly among the original remaining containers.)</i></p>
