Question

The total area of Egypt is 995,450 mi2. 19/20 of the area is desert. The remaining land is used for growing crops and is where civilizations are located. What is the area of the land that is desert? What is the area of the land that is usable? Write all of the given information that will help you solve this problem.

Answer 2

I dont know how to though. Thats what I need answered. @tkhunny

Answer 3

You must try something. Give the first one a go!

Answer 4

I dont know how to solve it .... @tkhunny I've tried a million times and it gets me nowhere.

Answer 5

You have the total area of Egypt. You have a ratio to split the land into two parts. How shall that be accomplished?

Answer 6

I dont know @tkhunny

Answer 7

That's just not good enough. You absolutely must do better than that. It won't fall out of the sky. You must give it some thought.

What section are you studying? Ratios? Percentages? Sets?

Answer 8

Im no longer on this. It has to be turned in by January 1st. Im now on planes.

Answer 9

@tkhunny

Answer 10

Fine. What section WERE you studying when you were given this problem? You must help, here. I must not do it for you.

Answer 11

I was studying Fractions at this time. @tkhunny Im homeschooled so i dont go by sections like public schools.

Answer 12

It matters not at all what path you take. What is important is that you understand what you are doing.

If we cut a pie into 10 pieces, and I eat 1/5 of the pie, how many pieces did I eat?

Answer 13

I dont understand how you get 1/5 out of 10 pieces.

Answer 14

@tkhunny

Answer 15

Very good. This is useful information.

Ever hear of "Equivalent Fractions"? Do you know that these fractions are the SAME?

1/3 = 2/6 = 15/45 = 70/210

Answer 16

So 1/5 equals 1/10 ?

Answer 17

No. That is not correct. 1/5 = 2/10. How can you know that?

Answer 18

I dont know, I was hoping somebody would explain it but also hint the answer at the same time.

Answer 19

You must know something about fractions. That's what we're doing, here - trying to fond out what you know about fractions.

So, how many pieces did I eat?

Answer 20

2

Answer 21

Good. How many pieces remain for someone else?

Answer 22

8

Answer 23

Establish: (1/5) * 10 = ???

Answer 24

1/5 * 10 = 2

Answer 25

One more, before we get back to Egypt.

(What) * 10 = 8

Answer 26

2/10

Answer 27

No, we already stated that (2/10) * 10 = (1/5) * 10 = 2

Try again.

Answer 28

it would then be 8/10...sorry ;/

Answer 29

Perfect. (8/10)*10 = (4/5)*10 = 8

Okay, we have a land mass. 19/20 is desert. What ratio represents the amount of land that is habitable or cultivated?

Answer 30

0.95 or 19:20

Answer 31

That's what 19/20 means, but that doesn't answer my question.

Answer 32

Im confused with what you're asking.

Answer 33

19/20 represents the ratio or portion of Egypt that is desert. 0.95 or 19:20
What represents the ratio or portion of Egypt that is NOT desert?

Answer 34

1/20 ???

Answer 35

Perfect. 1/20 = 0.05 = 1:20

Given:

Desert = 19/20 of Egypt and
Habitable = 1/20 of Egypt
How can we calculate the total land mass in each classification?

Answer 36

I thought we already did ? Sorry if im wasting time... @tkhunny

Answer 37

We absolutely did not do that. We cut up a pie. We have yet to cut up Egypt.

How can we calculate the total land mass in each classification?

Answer 38

Dividing ?

Answer 39

Maybe.

How did we do the pie?
10*(1/5) = 2
10*(4/5) = 8

Does that look like division or multiplication?

Answer 40

Multiplication..Thank you for being patient with someone like me.

Answer 41

I'm not complaining. I'm here to help.

995,450 mi2 * (WHAT) = Amount of Habitable Land
995,450 mi2 * (WHAT) = Amount of Desert

Answer 42

995,450 mi2 * 1/20 = amount of habitable land
995, 450 mi2 * 19/20 = amount of desrt

Answer 43

Perfect. Can you now do the multiplication?

Answer 44

You should notice that 1 + 19 = 20. This is NOT a coincidence.

Answer 45

49772.5 = 995,450 * 1/20
945677.5 = 955,450 * 19/20

Answer 46

Check your answer and see if it makes sense.

49772.5 + 945677.5 = ??? Do we get the original total back?

Answer 47

No...

Answer 48

It's probably because you used 955, rather than 995 in one of the multiplications. Try again until the total comes back.

Answer 49

i still get the same thing

Answer 50

Okay, let's try checking again. Do you get the original total?

995,450 * 1/20 = 49772.5
995,450 * 19/20 = 945677.5
49772.5 + 945677.5 =

Answer 51

I get 995,450 so yes.

Answer 52

There we go, then. You should now have enough information to answer the questions from the beginning. Do them in a different order.

Write the mathematical expression or expressions that you will use to solve this problem.

Carry out the operations carefully. Show all of your work.

Check your results.

Explain, using complete sentences, how you will solve this problem.

Answer 53

Thank you !! I really appreciate all your help <3 If I have anymore questions can I message you ?

Answer 54

Messaging is no good. Math expressions are too difficult in that environment. Just post to the public boards and tag me if you wish. I may still be here.

Answer 55

Im stuck on Part D...how would I write it ? @tkhunny Solve: (5 points) Carry out the operations carefully. Show all of your work.

Answer 56

How did you answer the other parts?

Answer 57

This is what I have so far;
A) You are being asked to find the area of land that is desert and area of land that is usable.

B) Total area of Egypt is 995,450 mi. 19/20 area is desert. I will solve this problem by multiplying and adding.

C) 995,450 * 1/20 = 49772.5

995,450 * 19/20 = 945677.5

49772.5 = 945677.5 = 995,450)

Answer 58

Can't really help you with that. You need to describe your process. Give it a go. Make it make sense.

Answer 59

ok

Answer 60

Thank you sooooo much for all your help. I apologize if i was whiny or annoying or snappy

Answer 61

No worries. It's not supposed to be easy. :-)
