Understanding Fractions and Decimals
Definition of Fractions
A fraction is a numerical value that represents a part of a whole. It is expressed as a ratio of two numbers, where the top number is called the numerator and the bottom number is called the denominator. The numerator represents the number of parts that are being considered, while the denominator represents the total number of parts in the whole. For example, in the fraction 3/4, the numerator is 3 and the denominator is 4. This means that the fraction represents three parts out of a total of four parts.
Definition of Decimals
A decimal is a numerical value that represents a part of a whole in a different way than a fraction. It is expressed as a number with a decimal point, where the digits to the left of the decimal point represent whole numbers, and the digits to the right of the decimal point represent parts of a whole. For example, the number 0.75 represents three-fourths of a whole. The digit 7 is in the tenths place, which represents 7/10 or 0.7, and the digit 5 is in the hundredths place, which represents 5/100 or 0.05.
