Answer:
5/12
Step-by-step explanation:
We know that Santos flipped the coin a total of 300 times. Out of the 300 times, he flipped 125 heads. We need to find a simplified ratio equivalent to:
125/300
First, a common factor is 5, so we can divide both sides by 5 to get:
25/60
We can divide it by more to simplify it down, so we can try another 5 to get:
5/12
5/12 would be the simpliest form
So 125/300 is equal to 5/12
Other forms: 5:12, 0.42, %42

Here, the reporter failed to eliminate any sort of possible bias which may be present, as all was sacrificed for the sake of convenience or ease.
