Question: A beadshop earns a third of its profit on Monday, a quarter of its profit on Tuesday and the rest of its profit on Wednesday. The shop makes a total profit of $1,200. How much profit, in dollars, was made on Wednesday?
Answer with step-by-step thinking: On Monday, 1200 / 3 = 400 dollars were made. On Tuesday, 1200 / 4 = 300 dollars were made. On Wednesday, 1200 - 400 - 300 = 500 dollars were made.
So the answer is 500.


Question: A portable computer drive has enough kilobytes of storage space to store 2000 photos. Each photo is 1.5 kilobytes in size. How many 200-kilobyte videos can it store if it already has 400 photos on it?
Answer with step-by-step thinking: The drive has 1.5 * 2000 = 3000 kilobytes of storage space. It already has 1.5 * 400 = 600 kilobytes of storage space taken up. Thus, it has 3000 - 600 = 2400 kilobytes of space left. The portable drive can store 2400 / 200 = 12 200 - kilobyte videos on it with 400 photos.
So the answer is 12.

Samuel received 3 / 4 of $240, which is $240 * (3 / 4) = $180. He spent 1 / 5 of $240, which is $240 * (1 / 5) = $48. He spent this amount from his own share, so he has $180 - $48 = $132 left.
So the answer is 132.
