OpenStudy (anonymous):

is my answer -4/10

OpenStudy (solomonzelman):

yes

OpenStudy (mathmate):

@rsdod6 The answer is correct for difference, but you need to simplify, i.e. reduce the fraction to its simplest terms. \(Example:\) 8/16=1/2

OpenStudy (anonymous):

so how to reduce to its simplest form

OpenStudy (solomonzelman):

4 and 10 can be both divided by 2.

OpenStudy (anonymous):

so now myanswer will be 2/5

OpenStudy (solomonzelman):

it is negative

OpenStudy (solomonzelman):

you had -4/10 ---> and get : -2/5.

OpenStudy (anonymous):

so -2/5

OpenStudy (solomonzelman):

yup

OpenStudy (anonymous):

thanks
