OpenStudy (ffrocks3):

Im here ;)

OpenStudy (ffrocks3):

OpenStudy (ffrocks3):

In a bag containing black and white marbles, ? of the marbles are black.

OpenStudy (anonymous):

oh is 3/8

OpenStudy (ffrocks3):

kk :)

OpenStudy (anonymous):

what does "m8" mean?

OpenStudy (ffrocks3):

Mate

OpenStudy (anonymous):

oh

TheSmartOne (thesmartone):

so if 3/8 marbles are black that means out of a total of 8 marbles then 3 are black.

TheSmartOne (thesmartone):

And you would just subtract 8-3 to get how many white marbles there are.

OpenStudy (anonymous):

4

TheSmartOne (thesmartone):

Are you sure the number is 3/8 ?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so is a a b or c or d?

TheSmartOne (thesmartone):

oh I get it now lol

OpenStudy (anonymous):

ok

TheSmartOne (thesmartone):

So the ratio of black to white marbles is 3 to 5 So now you have to see if any of the answer choices have the same ratio

TheSmartOne (thesmartone):

for example A is 3 to 8 so that is not correct.

OpenStudy (anonymous):

true

TheSmartOne (thesmartone):

And for example C is 20 to 12 if we simplify that we get 5 to 3 so that is wrong also

TheSmartOne (thesmartone):

So what is it now? @PlanSlam @~

OpenStudy (anonymous):

b,d

OpenStudy (anonymous):

oh i mean b

OpenStudy (anonymous):

righty?

TheSmartOne (thesmartone):

there can only be one answer -_-

OpenStudy (anonymous):

i know i said B. XD

TheSmartOne (thesmartone):

It is B. lol

OpenStudy (anonymous):

Right? @TheSmartOne

TheSmartOne (thesmartone):

I said it was right...

TheSmartOne (thesmartone):

No problem @PlanSlam

TheSmartOne (thesmartone):

*sarcasm intended* :P
