We encounter ideas related to fractions, decimals, ratios and percents on a daily basis. Confident and flexible understanding of these ideas are key to everyday estimation and mental calculation in contexts as diverse as shopping and budgeting, diluting mixtures, understanding scales on maps, interpreting probabilities and odds, and converting among metric units.
Not only is understanding these ideas essential to being numerate they are also foundational to more sophisticated mathematical ideas. If you understand fraction, decimals, ratios and percents you have the basis for understanding topics such as similarity, trigonometry, coordinate geometry, and fancy algebra

Fractions, decimals and percentages are related and can be used to express the same number, or proportion in different ways.
An understanding of percent relationships helps us to compare and represent increasing and decreasing proportions.
