Math this round we focus on the rates and a little introduction of the pre-algebra. One of the most challenging parts of this round is to solve a problem in the rate problem. I want to share this with you so that if you have any problem with it this strategy can help you. so that problem is some things like this It takes 15 minutes for 5 people to pain 3 wall. How long will it takes for 5 people to paint 5 walls? It’s just driving me so crazy just to solve this problem. However, I did it. Anyway, let’s get started. the first step you need to find is you want to find if you need to know how much does it need for 5 people to paint 1 wall. The way you need to do is take 15 divided by 3 so it 5. That means it takes 5 minutes for 5 people to paint 1 wall. and then you want to find how much does it take for 1 people to paint 1 wall. which you take. 5 times 5 which equal 25. then we know that it takes 25 minutes for 1 people to paint 1 wall. then you need to find how long does it takes for 1 people to paint 5 walls. so we take 25 times 5 which equates to 125 . after that we want to find 5 people to paint 5 walls which we take 125 and divided by 5 which make the value back to 25 minutes. The answer is it takes 25 minutes for 5 people to paint 5 walls.
Sees follow step by step and you will find the answer.
