Study Notes
Conversion of Measurements
- Familiarity with Information Sheet 1.2-2 is necessary before proceeding to Self-Check 1.2-2 and Task Sheet 1.2-1.
Ratio, Proportion, and Percentage
- Review Information Sheet 1.2-3 and complete Self-Check 1.2-3 after understanding the material.
Fractions, Percentage, and Decimals
- Information Sheet 1.2-4 provides details on this topic; complete Self-Check 1.2-4 and perform Task Sheet 1.2-2 after reviewing.
Four Fundamental Operations
- Essential mathematical operations: addition, subtraction, multiplication, and division.
- Mastery of these operations is crucial for understanding advanced mathematical concepts.
Addition
- Combining two or more numbers (addends) results in a sum.
- Example: 6 + 3 = 9, where 6 and 3 are addends, and 9 is the sum.
Subtraction
- Operation of taking one number away from another.
- First number is the minuend, second is the subtrahend, resulting in the difference.
- Example: 9 - 3 = 6, where 9 is the minuend, 3 is the subtrahend, and 6 is the difference.
Multiplication
- Represents repeated addition of a number.
- Numbers involved are called factors; the outcome is the product.
Systems of Measurement
- Two primary measurement systems: English and Metric.
- English system originated in England; Metric system originated in France.
- Basic metric unit: meter (100 centimeters = 1 meter).
Measurement Units
- Units in the Metric System: millimeters (mm), centimeters (cm), decimeters (dm), meters (m).
- Units in the English System: inches (in) and feet (ft), with divisions for smaller measurements.
Ratios
- Ratios express the relative size between two quantities.
- Written as “ratio of a:b” or in fractional terms; units are not involved.
- Example: A ratio of 1:2 indicates a size relationship.
Proportion
- Indicates the equality of two ratios or fractions.
- Example: If 20m of rope weighs 1kg, then 40m weighs 2kg, maintaining proportionality.
Interpreting Scale Drawings
- Scale communicates the size of drawings in relation to actual objects.
- Example: A scale of 1:5 signifies that one unit on paper represents five units in reality.
Fractions and Decimals
- Fractions represent parts of a whole, consisting of a numerator (top) and denominator (bottom).
- Example: In a collection of 5 children, if 3 are girls, the fraction of girls is 3/5.
Equal and Unequal Parts
- Recognizing fractions requires dividing a collection or whole into equal parts for accurate representation.
