The formula to calculate the ratio from a decimal (R) is:
\[ R = D \times 100 \]
Where:
A ratio is a way to compare two quantities by using division. It shows how many times one value contains or is contained within the other. Converting a decimal to a ratio helps in understanding the relationship between the two quantities in a more intuitive way.
Let's consider an example:
Using the formula to calculate the Ratio:
\[ R = 0.75 \times 100 = 75 \]
This means that the ratio is 75.
