Fetch length calculation for bowen ratio

WebMar 10, 2024 · Ratios should always be presented in their simplified form. When you are trying to understand how to calculate a ratio, make sure that you simplify a ratio by dividing both sides by the highest common factor. For example, 12:4 simplified would be 3:1 – both sides of the ratio divided by 4.
