Decimal numbers and percentages are important mathematical concepts used to represent parts of a whole. Decimal numbers and percentages allow for the precise notation of values that are not whole numbers and express ratios in the form of hundredths or using a decimal point. Decimal numbers and percentages are closely related, as the same values can be represented in both forms depending on the needs of mathematical procedures.
Decimal numbers are numbers written with a decimal point that separates the whole part of the number from its decimal part. Decimal numbers are an extension of natural and whole numbers (integers), as they allow for the notation of values between two whole numbers. In decimal numbers, each position to the right of the decimal point represents a smaller part of the whole, such as tenths, hundredths, and thousandths. Decimal numbers are ordered according to specific rules, where the placement of the decimal point determines the size of the number and its meaning in the numerical notation. Such notation allows for the precise representation of smaller values and accurate measurements.
Decimal numbers are compared, ordered by size, and used in various arithmetic operations, where care must be taken to correctly align the decimal places. Decimal numbers are an essential part of the number system, as they fill the space between whole numbers and allow for a detailed representation of numerical values.
Percentages are a way of writing parts of a whole, where the whole is represented by the number one hundred. Percentages are expressed with the symbol % and indicate how many parts out of one hundred a certain value represents. With percentages, we always work with ratios and proportions relative to one hundred units. Percentages allow for a simple representation of ratios, as they convert values into hundredths, which makes it easier to compare numerical data.
Percentages are directly related to decimal numbers, as any percentage can be expressed in decimal form and vice versa. When converting percentages to decimal numbers, we divide by one hundred, while decimal numbers are converted to percentages by multiplying them by one hundred. Percentages are useful for showing increases, decreases, and other mathematical procedures where we want to determine the share of a selected value.
Decimal numbers and percentages form an important link in expressing parts of a whole in different forms. Decimal numbers and percentages are closely related concepts, as they allow for conversion between notations that represent the same values in different ways. Understanding decimal numbers and percentages is crucial for correctly handling mathematical expressions where parts of whole values appear, as this ensures accuracy and consistency in numerical representations.
