6th Grade Math
posted by Missy .
I really don't know what to do on this question. If someone could start me off I could probably get the answer. Remember I am in 6th grade.
Dani has a sack of 50 pens. Of these, 10 are black, 15 are blue, and the rest are red. If she grabs a handful of 5 pens, how many would you expect to be black.

Since 10 pens out of 50 is 10/50, we can reduce this fraction to 1/5.
How many pens out of 5 would you expect to be black? 
I DON'T GET IT

So would it be 20 pens?

But Dani only grabbed 5 pens.

So would it be 1?

Right! :) You'd expect 1 black pen out of 5 pens.

well done!

[3X(3)4X(2)+5X2]+[2X(3)+8X(2)8X2]

[1st number]2+[2ndnumber]2=794 [13]2+[x]2=794 169+x2=794 x=794=169 x=2 625 x=2 625 x=625 5 625 5 125 5 25 5 5 1
