Answer:

Equation: 24 - 2p = 10

Pencils she bought: 7 pencils

Explanation:

Let number of pencils be p

initial money - cost of pens = final money

24 - 2p = 10

Solve this to find pencils she bought:

24 - 2p = 10

-2p = 10 -24

-2p = -14

p = 7

So she bought 7 pencils in total.

About 4/10 of the population has blood type O+. What percent of the population has blood type O+?
fenix001 [56]

If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.
