Answer:
7:12 is the right answer.
Step-by-step 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.
