A good way to work with a ratio is to turn it into a fraction. Be sure to keep the order the same: The first number goes on top of the fraction, and the second number goes on the bottom. You can use a ratio to solve problems by setting up a proportion equation — that is, an equation involving two ratios. Sample questions

Write down the new simplified ratio. You are left with two new terms. The new ratio is equivalent in value to the original ratio, meaning that the terms in one ratio are in the same proportion as the terms in the other ratio. Note that the terms of the new ratio should not share any common factors between them (other than 1).

When two or more ratios are equal, they are proportionate. This can be represented in the equals sign or the colon symbol in two ways. As in a:b::c:d or $dfrac{a}{b}$= $dfrac{c}{d}$. The ratio remains unchanged if we multiply or divide each term in the ratio by the same number, the ratio remains unchanged.
