Study Notes
Multiplication of Fractions
- When multiplying fractions, multiply the numerators and denominators separately.
- Examples:
- For ( \frac{3}{5} \times \frac{1}{2} ), multiply to get ( \frac{3 \times 1}{5 \times 2} = \frac{3}{10} ).
- Reduce to lowest terms if applicable.
Mixed Fractions
- Convert improper fractions to mixed fractions by dividing the numerator by the denominator.
- Example: ( \frac{11}{4} = 2\frac{3}{4} ) since ( 11 \div 4 = 2) remainder (3).
Division of Fractions
- To divide fractions, multiply by the reciprocal of the divisor.
- Example: ( \frac{1}{6} \div \frac{3}{5} = \frac{1}{6} \times \frac{5}{3} = \frac{5}{18} ).
Operations with Whole Numbers and Fractions
- Convert mixed fractions into improper fractions before division.
- Example: ( 4 \div 2\frac{1}{2} = 4 \div \frac{5}{2} = 4 \times \frac{2}{5} = \frac{8}{5} ).
Applying Fractions
- Common operations include finding fractions of whole numbers.
- Example: Finding (\frac{1}{2}) of (24) equals (12).
Decimal Multiplication
- When multiplying decimal numbers, ignore decimal points initially and multiply as whole numbers, then adjust the decimal in the result according to the total decimal places.
- Example: ( 0.2 \times 0.3 = 0.06 ) derived from ( 2 \times 3 = 6) and moving the decimal two places left.
Area and Perimeter Calculations
- Perimeter of an equilateral triangle: All sides equal; perimeter = (3) times side length.
- Area of a rectangle: Length multiplied by breadth; for (7.1) cm (length) and (2.5) cm (breadth) area = (17.75) cm².
Division Context
- Dividing a fraction by a whole number involves multiplying the fraction by the reciprocal of the whole number.
- Example: ( \frac{3}{4} \div 2 = \frac{3}{4} \times \frac{1}{2} = \frac{3}{8} ).
Practical Applications
- Divide fractions and whole numbers to calculate real-world scenarios, such as distance covered or resources consumed.
- Example: If Vidya drank (2) out of (5) liters of water, the remaining amount consumed by Pratap can be calculated based on this information.
Understanding Proportions and Reduction
- Reduce fractions to their simplest form for easier calculations.
- Use shading and visual aids to understand fractions and their proportions, such as shaded parts in circles or triangles.
Exercises for Practice
- Involves skill-building by calculating fractions, mixed numbers, and using decimal operations through practical problems provided.
