Protsendiväärtused

Protsendiväärtused refers to the values of percentages. A percentage is a number or ratio expressed as a fraction of 100. The word "percent" comes from the Latin "per centum" meaning "by the hundred." The symbol for percentage is "%". For example, 50% means 50 out of 100, which is equivalent to the fraction 1/2 or the decimal 0.5.

Protsendiväärtused are used in many contexts, including statistics, finance, and everyday life. They are a common way to express proportions, changes, and relationships between quantities. For instance, when reporting election results, percentages are used to indicate the share of votes each candidate received. In finance, interest rates are expressed as percentages, and discounts are also calculated as percentages of the original price.

To calculate a protsendiväärtus, one can use the formula: (part / whole) * 100. For example, if a student scored 80 out of 100 on a test, their percentage score is (80 / 100) * 100 = 80%. If the same student scored 40 out of 50, their percentage score is (40 / 50) * 100 = 80%. Understanding and calculating protsendiväärtused is a fundamental mathematical skill.
