Question

Ms. Christen bought a package of pencils. Out of every 10 pencils​, 2 are black. If there are 40 pencils in the​ pack, what fraction of the pencils in the pack are​ black? What percent of the in the pack are​ black?

Answer 1

8/40(=2/10)

20%

Explanation:

The fractional probability is 2/10. Since we have 40 pencils, we can do the following:

(2/10)*40, which gives us 8.

Therefore, 8 pencils will be black and the percentage would be (8/40)*100 = 20%
