1. Simplify multiple ratios

Simplifying a ratio may involve working with multiple ratios. If you are adding the ratios, ensure that the denominators are the same. For example, if you are given 2/3 and 1/2, the least common denominator is six. Divide this number by the denominator in the fraction, and multiply that result by the numerator. If you are asked to multiply two ratios, use cross-multiplication. To do this, multiply the numerator of one ratio by the denominator of the other. Do this for both numbers.

2. Simplify a single ratio

Simplify a single ratio by ensuring that it is in the lowest common form. For example, 4/16 can be reduced because 16 is a multiple of 4. Dividing both terms by 4 produces a new ratio of 1/4. This reduction typically involves a whole number without decimal spaces. Therefore, you cannot reduce a ratio like 2/7 any further.

3. Calculate the result

Calculate the result to finish the conversion. For simple ratios, such as 1/4, you may know the answer offhand and won't need a calculator. For more difficult ratios, you may need a calculator to ensure accuracy.

The multiplication of percentages is accomplished by converting the percentage to decimals, and multiplying the decimals. To convert a percentage to a decimal, the percent sign must be removed, and the number divided by 100. The decimal point should always be moved two places to the left when dividing by 100. After dividing 75 by 100, the answer is 0.75.
