OpenStudy (mertsj):

How many quarters does tony have?

OpenStudy (anonymous):

6 right

OpenStudy (mertsj):

How many dimes?

OpenStudy (anonymous):

5

OpenStudy (mertsj):

How many nickels?

OpenStudy (anonymous):

14??

OpenStudy (mertsj):

How many coins in all?

OpenStudy (anonymous):

14+5+6= 25

OpenStudy (mertsj):

So if you select one coin from a pile of 25 coins and 14 of them are nickels, what is the probability that you will select a nickel?

OpenStudy (anonymous):

do you divide

OpenStudy (anonymous):

or make it into a fraction

OpenStudy (mertsj):

You write the appropriate fraction.

OpenStudy (mertsj):

What is it?

OpenStudy (anonymous):

so its 14/25 but you cant really divide anything witht the two numbers since you cant divide them with a number

OpenStudy (mertsj):

The probability is 14/25
