Out of 20 cookies, 4/ 5 are chocolate chip. How many cookies are chocolate chip?

16

Step-by-step explanation:

We can solve this by using the equation: 4/5 x 20 = y

(y is the answer)

Now we can solve it. You can just solve 4/5 x 20, or if you like using decimals you can change it to 0.8 x 20, becaues 4/5 is equivalent to 0.8.

0.8 x 20 = 16.

Therefore, out of the 20 cookies, 16 are chocolate chip.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
