Here's an example of the type of word problem you'll see when you take the HiSET. "Mrs. Patterson's classroom has sixteen empty chairs." Notice how they didn't actually put the number, they spelled it out, because they're hoping you'll miss that, read carefully. "All the chairs are occupied when every student is present. If two-fifths of the students are absent, how many students make up her entire class?" Okay so, here they gave us this ratio, or fraction that we can use. And it's two out of every five students are absent. So, you have two absent to five total. Using this ratio and this third piece of information, we can set up a proportion. We have sixteen empty chairs. They're empty because there are sixteen students absent. Make sure you are consistent when you set up proportions. So if you first ratio is two absent to five total, then your second ratio should be sixteen absent to, and here's what we don't know, how many total. Now, there's more than one way to solve a proportion. Sometimes, you'll get a proportion that lends itself, like this one does, to just figuring out a pattern. For instance, what do you do to two to get sixteen? Well you just multiply times eight. So, be consistent. Do the same thing to your denominator. Five times eight is forty. So, there are forty total students. Well that's not how you spell that word. Okay... um... but, not all proportions can be solved that way. All proportions can however, be solved with cross-products. So, let me show you how to do that. You just cross-multiply. Two times "x" is "2x", and the cross products of every proportion are equal, so that equals five times sixteen, which is eighty, and then you simply solve for "x". So, divide both sides by two, and you still get that "x" is forty, and that there are forty, total, students in the class. There is an example of a word problem using a proportion to solve. Good luck on the HiSET. If you're planning on taking the HiSET exam, then you need to be ready for word problems. Here is an example of the type of word problem you'll see when you take the HiSET exam. "Jamie had six dollars and fifty cents in his wallet when he left home. He spent four dollars and twenty-five cents on drinks and two dollars on a magazine. Later, his friend repaid him two dollars and fifty cents that he had borrowed the previous day. How much money does Jamie have in his wallet?" Well, he's starting with six dollars and fifty cents. Then he spent four dollars and twenty-five cents, which means we need to take away four dollars and twenty-five cents from the six dollars and fifty cents. So, we subtract. That's two dollars and twenty-five cents, and two dollars on a magazine. That's more money that he spent. So, we need to take away another two dollars, which leaves him with just twenty-five cents, but then his friend repaid him two dollars and fifty cents, which means we added to the amount of money that he has. So, we add two dollars and fifty cents, which gives him two dollars and seventy-five cents. So, you just have to look for those key words like spent and repaid to make sure that you're doing the right thing, either subtracting or adding, depending on what you're doing. There you have one example of the type of word problem you'll see when you take the HiSET exam.
