Question

QUICK MATH PROBLEM!!!
(7^2 - 2^3) ÷ 7 =

Answer 1

Please don't give away answers. First figure out what 7^2 and 2^3 equal, subtract them and divide for 7. Order of operations.

Answer 2

CAN YOU WRITE IT AS A FRACTION OR INTERGER?

Answer 3

anyone?

Answer 4

Fraction

Answer 5

I need help w a fraction or interger. ;^;

Answer 6

do you know how to change a decimal into a fraction?

Answer 7

I forgot, okay. Can you help me?

Answer 8

please???

Answer 9

Yeah sure

Answer 10

Thank you soo much!!

Answer 11

Ok but sorry if I suck at explaining

Answer 12

It's fine. :)

Answer 13

So what place is the 9 in

Answer 14

the top place right?

Answer 15

What do you mean by "CAN YOU WRITE IT AS A FRACTION OR INTERGER?"? The decimal answer that the user above gave you is an approximation. What are you trying to do, exactly?

She gave you the fraction, and then use a calculator to approximate the decimal (why, I don't know... I would never approximate an exact answer unless there was a good reason to!!).

But if you know convert that approximate decimal BACK into a fraction, it won't be the original answer.

Answer 16

oh, now that answer is gone... lol... But I'm still not sure what you're trying to ask.

Answer 17

I'll write out the whole problem, okay. :)

Answer 18

Give me sec.

Answer 19

Yes, that's always best. :)

Answer 20

I think they're trying to ask how to turn a decimal into a fraction? but idk

Answer 21

I don't think so, not if it's this same problem. No reason even to be talking about decimals. :)

Answer 22

(7^2 -2^3) / 7 = ? Type a integer or a simplified fraction.

Answer 23

That what it says.

Answer 24

OK, well, if you get an answer that reduces to an integer, then you have an integer answer. Otherwise, you'll have a fraction.

Answer 25

It's just saying to "fully reduce" the fraction. If that turns out to be an integer, then that's what it will be. (Integers are the "whole numbers" and the "negative whole numbers", plus 0, e.g..... .... -3, -2, -1, 0, 1, 2, 3......)

Answer 26

@DebbieG are you good with proofs?

Answer 27

but the answer it like this, 5.857142857142857 ok, so I need to turn it to a fraction simplified right?

Answer 28

proofs?

Answer 29

Haha sorry not related to your question, you'll learn it in geometry

Answer 30

So just follow PEMDAS:
\((7^2 - 2^3) ÷ 7 \)

The P is for Parentheses, so do what's in the ( ) first. And E is for exponents, which come before S for subtraction. So evaluate the exponents, then subtract the result. Then THAT result gets divided by 7, which is really just the same as making it the num'r of a fraction over 7 in the den'r.

Answer 31

Thank you the both of you for trying to help me!!! ^^ and @itsKaylee Oh. You had me going for a second, like 'what is proofs??'

Answer 32

NO, let's get one thing straight!! :) You said:
"but the answer it like this, 5.857142857142857 ok, so I need to turn it to a fraction simplified right?"

What you mean is that you punched this up in a calculator and that's what it gave you. You can never turn that back into a simplified fraction because it is only an APPROXIMATE RESULT. You need to put your calculator ASIDE, this problem does NOT require it so don't reach for it! It's a crutch! :) Just do as I said above and you will end up with a fraction!

Answer 33

@itsKaylee it would depend on the subject of the proof, but in geometry, it's kind of doubtful... unless it's pretty basic. :) It's not one of my stronger areas. But just post your question, I can look at it and I'm sure someone here will be able to help you! :)

Answer 34

Okay, I'm going to try it without a calculator now. Give me a sec. No calculator remember.

Answer 35

Ok I'll just tag you in the question

Answer 36

41/7
Help?

Answer 37

RIGHT, go for it! :) Remember that a fraction is really just another way to write division, so the problem is really:

\[\Large (7^2 - 2^3) ÷ 7=\dfrac{ (7^2 - 2^3) }{ 7 }\]

So evaluate that numerator (the top) using the PEMDAS rules, and "put it over" a den'r of 7, THAT'S your fraction. The only other thing is to be sure that it is fully reduced. As long as it is, that's your simplified fraction! :)

Answer 38

YES, exactly!! See, you got it! NO calculator, even!! :)

Answer 39

And since 41 isn't a multiple of 7, there is nothing to reduce... so that's it, you're done!

Answer 40

OHHHHH!!!! THANK YOU!!! WOW, THANK YOU, OK, I GET NOW, WOW THANNK YOU!

Answer 41

You're very welcome, happy to help. :)

Answer 42

Thank you again! :) Bye! @DebbieG
