Question

Santos flipped a coin 300 times. The coin landed heads up 175 times. Find the ratio of heads to total number of coin flips. Express as a simplified ratio.

Answer 1

175:300 but it simplifies all the way down to 7:12

Answer 2

7:12 is the right answer.

Explanation:

Number of times Santos flipped the coin = 300

Number of times the coin landed heads up = 175

We have to find the ratio of heads to total number of coin flips, this means 175:300.

Simplifying this we get,

Divide both the numbers by 5, we get 35:60

Again divide both the numbers by 5, we get 7:12

Now, this cannot be simplified further as it does not have a common factor. So, 7:12 is the right answer.
