When calculating a ratio to a percentage, what is done after forming a fraction?

1. Add the numerator and denominator

2. Do long division using the denominator as the outside number

3. Multiply the denominator by 100

4. Subtract the whole number from the fraction

The correct answer is: Do long division using the denominator as the outside number

To convert a ratio into a percentage, after forming a fraction, you perform division. This involves dividing the numerator by the denominator, which is the step referred to in the choice that states you do long division using the denominator as the outside number. This process gives you a decimal value, which you can then convert into a percentage by multiplying by 100. Once you have the decimal result from the division, multiplying by 100 allows you to express that decimal as a percentage, which is a common way to interpret ratios in everyday contexts. This method is key to accurately determining the percentage value that corresponds to the ratio you started with.
