Understanding Fractions
A fraction is a mathematical expression that represents a part of a whole. It consists of two numbers, the numerator and the denominator, separated by a horizontal line. The numerator is the number above the line and the denominator is the number below the line. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator.
Fractions can be expressed in different forms, such as proper fractions, improper fractions, and mixed numbers. A proper fraction is a fraction where the numerator is less than the denominator, such as 2/3. An improper fraction is a fraction where the numerator is greater than or equal to the denominator, such as 5/3. A mixed number is a number that consists of a whole number and a proper fraction, such as 1 1/2.
Fractions can be added, subtracted, multiplied, and divided. To add or subtract fractions, the denominators must be the same. To multiply fractions, multiply the numerators and denominators separately. To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
Scientific calculators can be used to perform calculations with fractions. To enter a fraction on a scientific calculator, enter the numerator, press the division key, and then enter the denominator. Some scientific calculators may have a specific key for entering fractions.
Understanding fractions is essential for performing calculations with them. By knowing the different forms of fractions and how to perform calculations with them, individuals can solve various mathematical problems involving fractions.
