Question

Peter gets 1 star for every 3 correct answers he gets on khan academy. What is the minimum number of correct answers Peter must enter if he wants to get 12 stars?

For full points you need to write an equation that uses a variable and division, show what work you did to solve it, and then give me a final answer.

Answer 1

Peter needs to get 36 problems correct to get 12 stars

Explanation:

for every 3 correct answers, Peter gets 1 star

1/3

if he wants 12 stars he will have to get 'x' amount of questions correctly

considering this is constant, 1/3 will have to equal 12/x

`(1)/(3) = (12)/(x) \\\\1x = 36\\`

1x = x, so you don't need to do anything to 36

therefore the answer is that you need to get 36 problems correct to get 12 stars
