Ms. Stephanie bought a package of pens. Out of every 10 pens, 1 are black. If there are 30 pens in the pack, what fraction of the pens in the pack are black? What percent of the pens in the pack are
black?
What fraction of the pens in the pack is black?

The fraction of the black pens in the pack is

The percent of the black pens in the pack is 10%

Step-by-step explanation:

If 1/10 pens are black, we can use this same proportion to find how many black pens will be in the pack of 30.

Using this, there will be 3/30 pens that will be black, since 3/30 is equivalent to 1/10 when reduced.

So, the fraction of the black pens in the pack is

To find the percent, divide 3 by 30:

3/30

= 0.1 (10 percent)

So, the percent of the black pens in the pack is 10%

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
