Study Notes
Fractions
Fractions represent parts of a whole. They can be used to describe portions of items, such as the fraction of a pizza you want to eat or the fraction of a pie. Fractions are also used to describe ratios of quantities and can be used to represent numbers in other number systems. In mathematics, fractions are used to describe the relationship between two numbers, one of which is a multiple of the other.
Multiplying Fractions
To multiply fractions, you can use the following steps:
- Determine the least common multiple (LCM) of the denominators. The LCM is the smallest number that both denominators can divide into.
- Multiply the numerators of the fractions. The result is the new numerator.
- Divide the result by the LCM. The result is the new fraction.
Dividing Fractions
Dividing fractions can be done by multiplying the dividend by the reciprocal of the divisor. The reciprocal of a fraction is found by swapping the numerator and denominator. For example, the reciprocal of 1/2 is 2/1, which can be simplified to 1.
Fraction Word Problems
Fraction word problems are situations where fractions are used to describe a real-life situation. These problems can be solved using the same methods as other fraction problems, such as multiplying or dividing fractions.
Fraction Operations
Fraction operations include addition, subtraction, multiplication, and division. These operations can be done using the rules of arithmetic, such as the distributive property and the order of operations.
Fraction Simplification
Fraction simplification involves reducing a fraction to its simplest form by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD is the largest number that can divide both the numerator and denominator evenly.
In summary, fractions are used to describe parts of a whole, and they can be combined, divided, and simplified using the rules of arithmetic.
Learn about different operations involving fractions, such as multiplication, division, addition, and subtraction. Explore how to simplify fractions to their simplest form by reducing them to their common factors. Solve fraction word problems that involve real-life scenarios using fraction arithmetic techniques.
