Understanding Fractions, Decimals, and Percentages
Fractions, decimals, and percentages are essential concepts in mathematics, and being able to convert between them is a vital skill. In this article, we will explore the basics of fractions, decimals, and percentages, and provide a comprehensive guide on how to convert between them.
Fractions
A fraction is a way of expressing a part of a whole. It consists of two numbers: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, and the denominator tells us how many parts the whole is divided into.
For example, the fraction 3⁄4 can be thought of as 3 equal parts out of a total of 4 parts.
Decimals
A decimal is a way of expressing a fraction using a point. It is a number with a whole part and a fractional part. The fractional part is separated from the whole part by a decimal point.
For example, the decimal 0.75 can be thought of as 75⁄100, which is equivalent to the fraction 3⁄4.
Percentages
A percentage is a way of expressing a fraction with a denominator of 100. It is a number with a % symbol, which represents the number of parts per 100.
For example, the percentage 75% can be thought of as 75⁄100, which is equivalent to the fraction 3⁄4.
Converting Between Fractions, Decimals, and Percentages
Now that we have a basic understanding of fractions, decimals, and percentages, let’s learn how to convert between them.
Converting Fractions to Decimals
To convert a fraction to a decimal, we need to divide the numerator by the denominator.
For example, to convert the fraction 3⁄4 to a decimal, we would divide 3 by 4, which gives us 0.75.
Converting Decimals to Fractions
To convert a decimal to a fraction, we need to find the equivalent fraction by dividing the decimal by 1.
For example, to convert the decimal 0.75 to a fraction, we would divide 0.75 by 1, which gives us 3⁄4.
Converting Percentages to Decimals
To convert a percentage to a decimal, we need to divide the percentage by 100.
For example, to convert the percentage 75% to a decimal, we would divide 75 by 100, which gives us 0.75.
Converting Percentages to Fractions
To convert a percentage to a fraction, we need to find the equivalent fraction by dividing the percentage by 100.
For example, to convert the percentage 75% to a fraction, we would divide 75 by 100, which gives us 3⁄4.
Converting Decimals to Percentages
To convert a decimal to a percentage, we need to multiply the decimal by 100.
For example, to convert the decimal 0.75 to a percentage, we would multiply 0.75 by 100, which gives us 75%.
Converting Fractions to Percentages
To convert a fraction to a percentage, we need to find the equivalent percentage by multiplying the fraction by 100.
For example, to convert the fraction 3⁄4 to a percentage, we would multiply 3⁄4 by 100, which gives us 75%.
📝 Note: When converting between fractions, decimals, and percentages, it's essential to remember that the denominator of a fraction should always be a non-zero number, and the percentage should always be between 0 and 100.
