Question 1207697
<br>
Another approach, which I personally find easiest and fastest....<br>
Given: 3 people can paint 2 rooms in 4 days<br>
New data: 12 rooms instead of 2
That's 6 times as many rooms; 6 times as many people are needed: 3*6 = 18 people<br>
New data: 6 days instead of 4
That's 3/2 as many days; 2/3 as many people are needed: 18*(2/3) = 12<br>
ANSWER: 12 people can paint 12 rooms in 6 days<br>
Short solution, without all the words:
3*6*(2/3)=12<br>
