OpenStudy (anonymous):

-4 1/5 - -13 1/10

OpenStudy (anonymous):

Be 100% sure of ur answer

OpenStudy (anonymous):

PLZ

OpenStudy (anonymous):

Now first what i would do is change it from subtraction a negative to adding a positive like this : -4 1/5 + 13 1/10

OpenStudy (anonymous):

So now you know it would be a positive

OpenStudy (anonymous):

Now find the lowest common denominator

OpenStudy (anonymous):

What is the lowest common denominator?

OpenStudy (anonymous):

Um...

OpenStudy (anonymous):

idk 5?

OpenStudy (anonymous):

Whats the lowest denominator that they could both have example: 1/4 and 1/8 Lowest common denominator is 8

OpenStudy (anonymous):

it should be five the lowest common denominator 5 and 10 have is 5

OpenStudy (anonymous):

It wouldnt be five because 1/10 cant be divided by 2.

OpenStudy (anonymous):

What would it be?

OpenStudy (anonymous):

hello?

OpenStudy (anonymous):

What would it be?

OpenStudy (anonymous):

Do you know?

OpenStudy (anonymous):

Let me explain this better Lowest Common Denominator is the lowest number both 5 and 10 an be divided by

OpenStudy (anonymous):

What would that be?

OpenStudy (anonymous):

Hmm i guess 10?

OpenStudy (anonymous):

yeah.

OpenStudy (anonymous):

So it would be -4 2/10 + 3 1/10

OpenStudy (anonymous):

13 1/10 sorry

OpenStudy (anonymous):

is it -8 9/10?

OpenStudy (anonymous):

Now add that fractions but remember 4 2/10 is negative

OpenStudy (anonymous):

Its 13 not 3 sorry

OpenStudy (anonymous):

And its not 9/10

OpenStudy (anonymous):

its k

OpenStudy (anonymous):

OH

OpenStudy (anonymous):

is it -17 3/10?

OpenStudy (anonymous):

NO you were close and it is 9/10 sorry did my math wrong

OpenStudy (anonymous):

My fault

OpenStudy (anonymous):

Ok back to -8 9/10 thats so close but wrong in one way

OpenStudy (anonymous):

Im kinda laggin i think

OpenStudy (anonymous):

or wait 17 3/10?

OpenStudy (anonymous):

OpenStudy (anonymous):
