GED Questions from Jesse

Jesse writes:I was wondering If u could let me know if I got these two questions correct I’m taking my ged next week & I want to feel comfortable with this math.
On a map 1/3 in=15 miles find the distance between two towns on a map that equals 3 2/3 in. How many miles r between the two? my answer was 75 miles am I correct?Next Question

The scale on a map indicates that 1/2 inch represents an actual distance of 120 miles, how far apart will two towns be if the actual distance between them is 180 miles my answer was 2 inches am I correct? if not could u explain how to set up these type of problems? thank you, Jesse.

Jesse,

Hey! Congrats on your GED test comin’ up. Y’know what these questions are? Ratios. I got a ratio post on my blog at: http://www.passged.com/student_blogs/curtis/2007/12/24/rice-ratios-gotta-love-that-ged-math/

There’ll prolly be a ratio question on the GED test. Here’s how it works. Take the first question. You got 1/3 inch, that equals 15 miles. Picture it in your head. Say this line is 1/3 inch: |—| It be 15 miles.

So, you got to find out how many miles in 3-2/3 inch. Well, first you gotta find out, how many 1/3-inches are in 3-2/3 inch. Get it?

Three 1/3-inch lengths are in 1 inch, like this:
|—|—|—|

So, in 3-2/3 inches, there’s 11 1/3-inch lengths:
|—|—|—|
|—|—|—|
|—|—|—|
|—|—|

Each 1/3-inch is 15 miles, right? So, we got 11 lengths of 15 miles… that’s 15 times 11, and that’s 165 miles! There ya go. Always makes it easier to understand to picture it in your head.

If you want to do it mathematically, what I did was set up a ratio:
1/3:15
3-2/3:x

Divide 3-2/3 by 1/3… then multiply 15 by the answer to get x.

Here’s the other one.
1/2 inch = 120 miles
x = 180 miles

Same deal here, right? You got a ratio.
1/2 inch:120 miles
x:180 miles

The relationship between 120 and 180 got to be the same as between 1/2 and the answer. So, what’s the relationship between 120 and 180? If you divide 180 by 120, 180/120 = 18/12 = 9/6 = 3/2 = 1-1/2

So, 180 is 1-1/2 times 120. Then x got to be 1-1/2 times 1/2. That’s 3/4. If it’s easier, you can do 1.5 x .5 = .75 …same thing. So, the answer’s 3/4 inch. Get it?

Hope this helps!

Curtis

GED Social Studies Important Idea: Separation of Powers

On the GED test, there are some important ideas you need to know about government and the big ideas behind government in the U.S. I was thinking about the last thing I talked about, redistricting, made me think about it. I mean, when people were using redistricting to discriminate against blacks or other minorities, other people brought it to court. The Supreme Court decided whether the people making laws were right or wrong. So, one part of the government can stop another part of the government from doing something. Continue reading

GED Practice Essay: Revising the Conclusion

Okay! I’m on the final step of revising my practice GED essay. That’s the conclusion. I think a good conclusion is really important on the GED. The GED readers look for organization, and a good conclusion shows good organization. The GED readers are also people…and people like a good conclusion. It leaves you with a good impression, since it’s the last thing you read. Continue reading

GED Vocabulary Building

I think that I’ve got to take a break from GED poetry for a while. It’s hard, right? One of the things that makes poetry hard, and some of the other reading on the GED is vocabulary. I’ve given some vocabulary advice for the GED test before, but I thought it would help to give some more advice on how to build your vocabulary…learn more words before you take the GED test.
