Ratio, Proportion, and Percent is a mathematical topic that compares quantities. Because the GED Math test focuses on checking your ability to apply math to real-life settings, you can expect word problems that ask you to find the ratio, proportion or percentage as these are used in everyday life.
A ratio is a comparison of two different quantities. For example, if strawberries cost $5/kg, oranges $2/kg, and grapes $4/kg, then the ratio of these prices can be expressed as 5:2:4. Ratio word problems usually ask you to compare two quantities or to determine proper allocation.
A proportion is an equation showing that two ratios are equal. A percent or percentage is a ratio or number expressed as a fraction of 100. Three percent, for example, is really a ratio that means 3 per 100.
Ratio, Proportion, and Percent are often used in cooking, shopping, and financial transactions and other real-life situations.
