Aconstruction company can remove 2/3 tons of dirt from construction site each hour how long will it take them to remove 30 tons of dirt from the site?

You would want to divide 30 by 2/3 so you would do 30/1 times 3/2. This method is known as keep change flip or kcf (Kentucky Chicken Fried is what some people say) your final answer should come out to 90/2 which simplified is 45. Hope this helped
