Jason bought a bag of mixed cookies and a gallon of milk. the bag of cookies contained 18 chocolate chip cookies and 20 oatmeal cookies. which of these shows the ratio of chocolate chip cookies to oatmeal cookies in the simplest form?

 9 : 10

Step-by-step explanation:

Given : Number of chocolate chip cookies  = 18

Number of oatmeal cookies = 20

We know that the ratio of A to B can be written as .

Then, the  ratio of chocolate chip cookies to oatmeal cookies will be written as

Since , 18 and 20 are multiple of 2 , so divide numerator and denominator by 2 , we get

, which is in the simplest form.

Hence, the  ratio of chocolate chip cookies to oatmeal cookies in the simplest form = 9 : 10.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
