Allison has 6 blue pencils and 10 yellow pencils. sadie has 24 pencils that are either blue or yellow. the ratio of blue pencils to yellow pencils is the same for both allison and sadie. how many blue pencils and yellow pencils does sadie have?

6 (Allison's number of blue) divided by 16 (Allison's total) is equal to x (Sadie's blue) out of 24 (Sadie's total).

So 6/16=3/8=x/24. So x=3*3, so Sadie's amount of blue pencils is 9. The rest of Sadie's pencils are yellow, so Sadie has 24-9=15 yellow pencils.

I think the answer to this question is 6:10?
