Explain simply why 12 is the correct answer to: Brandon has been fired from half the businesses in town and has quit from a third of them. If there are 72 business in town, how many businesses can he still apply to?. Explanation:
First divide the total number of businesses by 2 to find how many businesses Brandon hasn't been fired from: 72 businesses / 2 = 36 businesses. Then divide the total number of businesses by 3 to find how many businesses Brandon quit from: 72 businesses / 3 = 24 businesses. Then subtract that number from the number of businesses he hasn't been fired from to find the number of businesses where he can still apply: 36 businesses - 24 businesses = 12 businesses.
