Unit conversion is the process of converting the measurement of a quantity from one unit to another while maintaining the same quantity. It is fundamental to many fields, including science, engineering, construction, and daily life. Click on the link to learn more about Unit conversion and see examples.

Conversions with Currency - is the process of exchanging one currency for another based on an established exchange rate. The exchange rate tells you how much one currency is worth in terms of another. For example, if you’re traveling to another country, you’ll need to exchange your home currency (such as U.S. dollars) for the local currency (such as euros or yen) to make purchases while abroad.

Currency conversions are commonly used in international trade, travel, finance, and investments. When you understand how to convert between different currencies, you can compare prices, assess values, and make informed decisions, whether you’re buying something overseas or investing internationally.

Understanding Unit Price and Unit Rate - This page will help you fully understand the difference between unit price and unit rate, how to calculate each one, and why these concepts are important in real life.  

Percent Equation Method - is a simple and effective way to solve percent problems using the relationship between the part, percent, and whole. This method relies on the equation Part = Percent × Whole, where the percent is converted into a decimal, and the whole represents the total value. By substituting the known values for the part or the whole, you can quickly solve for the unknown variable. This method is beneficial when you're given a percentage and need to find either the part or the whole, making it an essential tool for quickly solving real-world percent problems. 

Proportion Method - is a mathematical approach used to solve percent problems by setting up a ratio, or fraction, that represents the relationship between the part, the whole, and the percent. This method is based on the idea that the percentage, when written as a fraction, can be compared to the part and the whole using a proportion Percent/100 = Part/Whole.
