Any help? I can not seem to figure this out.
There are 4 jars each with 96 screws in them. In one 1/4 is being used in another 5/8, in another 3/4, and the last one 1/2 what is the fraction of total screws not being used?
I was thinking that maybe the wording was wrong and it was supposed to be each can hold 96 screws.

I think in order to do much of anything with this, we will have to make some assumptions about what is meant.
SCENARIO A
Let’s assume each jar literally has 96 screws inside it; the screws “being used” are outside each jar; the fractions being used are fractions of each total inside and outside the jar; and the fraction of total screws not being used is the fraction of all screws inside and outside the jars. In that case:
Jar 1 has 96 inside and 32 outside in use.
Jar 2 has 96 inside and 57.6 screws outside in use –
No, that cannot be right.

Let’s try SCENARIO A again.
SCENARIO A
Let’s assume each jar literally has 96 screws inside it; the screws “being used” are outside each jar; the fractions being used are fractions of each total inside and outside the jar; and the fraction of total screws not being used is the fraction of all screws inside and outside the jars. In that case:
Jar 1 has 96 inside and 32 outside in use.
Jar 2 has 96 inside and 57.6 screws outside in use – sure, what the hell.
Jar 3 has 96 inside and 288 screws outside in use.
Jar 4 has 96 inside and 96 outside in use.
384 screws in the jars not being used; 857.6 total screws (or maybe 858 total screws).
384/858 = 64/143 = just under 0.448
384/857.6 = 30/67 = just under 0.448
Were any of –
384/858
384/857.6
3840/8576
64/143
30/67
0.448
.448
0.447 something
.447 something
– among the choices?

Ah, wait, I screwed up SCENARIO A a little bit.
Jar 2 has 96 inside and 160 screws outside in use; not 57.6 screws outside in use.
384/960 = fraction not in use; not 384/857.6 .
384/960 = 2/5 .
There’s the 2/5 .[/quote]
Why is the denominator 960?
And how do you not get a decimal for 5/8?

He’s taking it literally, that 96 screws is the fraction unused in each jar. So 96 is 1/4th of the total of #1, 5/8ths of the total of #2, and so on.
Doing it this way, 2/5ths is the answer.
I still think 15/32 should be the answer, and if they want a different answer they need to change the wording of the question.
