19 dozen cookies to individual cookies

Art [367]

Answer:

228 individual cookies.

Step-by-step explanation:

To convert 19 dozen cookies to individual cookies, we first have to identify that:

$dozen=12$

If a dozen is equal to 12, to solve, we simply must multiply the amount of dozens, which is 19, by a dozen, which is 12:

$19*12=$

$228$

Therefore, there are 228 individual cookies.

-

We can check our work by dividing the individual number of cookies, 228, by dividing buy the amount of dozens, 19, and a dozen, 12:

$228$ ÷ $19=12$

$228$ ÷ $12=19$

As you can see, our quotients are the two figures we started with, and when multiplied together, give us 228 individual cookies; therefore, our solution is correct!
