My question is: Marc bought 50 episodes of the show "Friends" online. Each day Marc watches 1/10 of the episodes he bought. How many days will Marc need to finish 50 episodes of the show he bought? Your thoughts:
Marc watches 50 * 1 / 10 = 5 episodes a day. So, he will need 50 / 5 = 10 days to finish all episodes he bought. The final answer: 10.
