A ratio is just a relationship, how many times one value contains or is contained within another. In your case, how many times heads is contained in the total number of coin flips. Since you had 175 heads in 300 coin flips, your ratio is 175 heads to 300 tosses or 175:300. Simplifying the ratio is just reducing it down, similarly to reducing a fraction. both sides of the ratio can be divided by 25, so the simplified form would be 7:12.
