Hi, I'm Rachel, and today we're going to be going over how to do arithmetic reasoning. While there's so many different problems that you can do, but the main thing you want to do is, if you have a problem with units, you want to put it into single units. What does that mean? That means that if you have a problem like a train is traveling at 300, it goes 300 miles in let's say six minutes, right? So, what is the train's speed per minute, right? Well, that's really fast, but okay, it's a very super fast train. So what is the train's speed per minute, mile per minute, right? So that means that you want to get it into single units. You want to know the train's speed in one minute. So, here if you're going six to one, right? You can divide six by six to get one. So, you can divide the numerator as well by one, 300 divided by six is going to be 50. So it's 50 miles per minute. So if they're asking, you know, how fast does is this super duper fast train from the future go, it goes 50 miles per minute. And that's just one example of arithmetic reasoning, you know, using that single units, right? The unit rate as we like to call it, unit rate, and we're reasoning, you know, what is going to be the miles per minute of a train knowing what we already know. And you apply it to the situation. I'm Rachel, and thank you for learning with me today.
