Question

Tameka bought three dozen donuts to take into work. There are 15 cake donuts, 6 glazed donuts, 6 chocolate donuts, and 9 blueberry donuts. If she randomly gives donuts to 12 of her coworkers, which of the following is the best prediction of the number of coworkers that will receive a cake donut? 5 6 2

Answer 1

Ratio of Cake Donuts to Total Donuts = 15/36

Let, the number of people with Cake donuts = x

Then, 15/36 = x/12

x = 12/36 * 15

x = 1/3 * 15

x = 5

In short, Your Answer would be: 5

Hope this helps!

Answer 2

Ratio of Cake donuts to Total donuts = 15/36
Since 12x3=36 and there are 15 cake donuts
Cake donuts = x
15/36 = x/12
x = 12/36 times 15
12/36 =1/3
x = 1/3 times 15
1 15. = 15
- x. - - = 5
3. 1 = 3
x = 5
