Which fractions are equivalent to -3/8 ?

OpenStudy (anonymous):

OpenStudy (anonymous):

@perl

OpenStudy (anonymous):

@perl hehehe as required.

OpenStudy (eric_d):

You can try to simplify all option ..

OpenStudy (anonymous):

@ChiefArnav how?

OpenStudy (eric_d):

if it's equivalent to -3/8 after simplifying, that option wld the answer

OpenStudy (anonymous):

@eric_d instead of simplifying, you can do backward: multiple both numerator and denominator by the same number and check which are the options.

OpenStudy (anonymous):

I mean \(-\dfrac{3}{8}*\color{red}{\dfrac{2}{2}}=-\dfrac{6}{16}\) oh yeah, the first option is ok, right?

OpenStudy (anonymous):

try one more \(-\dfrac{3}{8}*\color{red}{\dfrac{4}{4}}=-\dfrac{12}{32} \) but our option is 12/32, not -12/32, hence b) is not correct one. That's the way I solve this kind of problem

OpenStudy (anonymous):

Yes that and 12/32, Right,

OpenStudy (anonymous):

@elephantinair77 you do the leftover, hihihi...

OpenStudy (anonymous):

What if only the numerator is negative?

OpenStudy (anonymous):

no different, they are exactly the same.

OpenStudy (anonymous):

So A and B?

OpenStudy (eric_d):

No

OpenStudy (anonymous):

how about the last one?

OpenStudy (anonymous):

B are not correct

OpenStudy (anonymous):

A, B ,D, I have to go, give you the answers and you check by yourself

OpenStudy (eric_d):

B is incorrect because it's a positive value

OpenStudy (eric_d):

whereas -3/8 is a negative value

OpenStudy (eric_d):

@elephantinair77

OpenStudy (anonymous):

Could it be C?

OpenStudy (eric_d):

There are 3 answers Yes, C is one of it.

OpenStudy (anonymous):

So B is not one of the answers?

OpenStudy (eric_d):

Yup! Do you why ?

OpenStudy (anonymous):

No can you explain it to me?

OpenStudy (eric_d):

Because, 12/32 is a \(positive~ value\)

OpenStudy (eric_d):

whereas \(-3/8\) is a \(negative~value\)

OpenStudy (eric_d):

Get me @elephantinair77

OpenStudy (eric_d):

@elephantinair77

OpenStudy (eric_d):
