Can someone help?!

OpenStudy (anonymous):

OpenStudy (anonymous):

Do you know how to multiply fractions?

OpenStudy (anonymous):

not at all really :/

OpenStudy (anonymous):

im very bad at math

OpenStudy (anonymous):

Well look at 9 over 3 9/3 Is 9 divisble by 3?

OpenStudy (anonymous):

it is

OpenStudy (anonymous):

If so what is the answer to that

OpenStudy (anonymous):

3

OpenStudy (anonymous):

Okay so now you have -8 x -2/5 x 3

OpenStudy (anonymous):

Do you know how to simplify -2/5 ?

OpenStudy (anonymous):

divide it?

OpenStudy (anonymous):

You can, but you would get a decimal.

OpenStudy (anonymous):

yes i see that...so what would you do?

OpenStudy (anonymous):

Well what is the decimal?

OpenStudy (anonymous):

-2.5

OpenStudy (anonymous):

That wouldn't be it. Do -2 / 5.

OpenStudy (anonymous):

-0.4

OpenStudy (anonymous):

Okay so what you have now is -8 x -0.4 x 3

OpenStudy (anonymous):

now we multiply them?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

9.6?

OpenStudy (anonymous):

Or 9 3/5 as a fraction form.

OpenStudy (anonymous):

okay..can i ask another?

OpenStudy (anonymous):

Absolutely.

OpenStudy (anonymous):

it says multiply

OpenStudy (anonymous):

Okay, look at the problem. Are any of the fractions divisble?

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

Is there a whole number?

OpenStudy (anonymous):

-5

OpenStudy (anonymous):

Okay what about 8/-10 Can you simplify it?

OpenStudy (anonymous):

-0.8?

OpenStudy (anonymous):

Both of the numbers are divisible by a certain number. Find that number and divide.

OpenStudy (anonymous):

Keep it in fraction form

OpenStudy (anonymous):

what would it be in fraction form?

OpenStudy (anonymous):

\[\frac{ 8 }{ -10 } \div \frac{ 2 }{ 2 }\]

OpenStudy (anonymous):

4/-5

OpenStudy (anonymous):

Very good So now you have \[\frac{ -1 }{ 7 } \times \frac{ -5 }{ 1 } \times \frac{ 4 }{ -5 }\]

OpenStudy (anonymous):

ok so now what do we do?

OpenStudy (anonymous):

like how do u multiply it?

OpenStudy (anonymous):

Multiply all the numbers on top and tell me what you get

OpenStudy (anonymous):

20

OpenStudy (anonymous):

now do the bottom like that too?

OpenStudy (anonymous):

Good. Now do the same with the bottom.

OpenStudy (anonymous):

-35

OpenStudy (anonymous):

so itd be 20/-35

OpenStudy (anonymous):

So now you have \[\frac{ 20 }{ -35 }\] What goes into both of those? Find it and divide. To simplify it.

OpenStudy (anonymous):

5

OpenStudy (anonymous):

Good now simplify \[\frac{ 20 }{ -35 } \div \frac{ 5 }{ 5 }\]

OpenStudy (anonymous):

4/-7

OpenStudy (anonymous):
