Question

One pound of cashews and 2 pounds of peanuts are added to 3 pounds of a store-bought cashew/peanut mix. If the total is a 6-pound mix that is 2/5 cashews by weight, what fraction of the store-bought mix were cashews?

Answer 1

Woah.. confusing :/

Answer 2

Emily.. I don't know >:'( ....

Answer 4

Okay, @jigglypuff314, have to agree with @LovelyAnna that the question is phrased a little oddly. However, I think this may be what you are looking for:

\[\frac{ 1 }{ 3 }+x=\frac{ 2 }{ 5 }\]

Solve for x and I get:\[x=\frac{ 1 }{ 15 }\]

Answer 5

So sorry.. :(

Answer 6

@HomeschoolGrad that's what I got too
but the answer key had gotten 7/15 ...
do you have an idea of how they would have gotten that?

Answer 7

:S could it be a mistake in the answer key? You would be surprised how many times I've driven myself crazy just because of a mistake in an answer key.

Like I said though, the question is phrased a little weirdly. Maybe there is something we're not understanding. :(

Answer 20

its indeed 7/15

Answer 21

' 6-pound mix that is 2/5 cashews by weight'
means 6*2/5 = 12/5 pounds cashew in total.

1 pound was added to the mix,
so, 12/5-1 = 7/5 pound of cashew was already present in that 3 pound mix

7/5 pound in 3pounds gives the ratio of (7/5)/3 = 7/15
