A machine fills 150 cans of paint every 8 minutes. How many minutes does it take this machine to fill 675 cans?
To know how many groups of 150 cans there are in 675 cans, we calculate 675 / 150 = 
<gadget id="calculator">675/150</gadget>
<output>9/2 = around 4.5</output>
4.5.
For each of these groups, 8 minutes are needed, so it takes 8 * 4.5 = 
<gadget id="calculator">8*4.5</gadget>
<output>36</output>
36 minutes.
