Study Notes
Equivalent Fractions
- Equivalent fractions are fractions that have the same value, but different numerators and denominators.
- They can be created by multiplying or dividing both the numerator and denominator by the same number.
- Example: 1/2 is equivalent to 2/4, 3/6, etc.
Adding Fractions
- To add fractions, they must have the same denominator.
- If the denominators are different, find the least common multiple (LCM) and convert both fractions to have the LCM as the denominator.
- Add the numerators and keep the denominator the same.
- Example: 1/4 + 1/4 = 2/4 = 1/2
Subtracting Fractions
- To subtract fractions, they must have the same denominator.
- If the denominators are different, find the least common multiple (LCM) and convert both fractions to have the LCM as the denominator.
- Subtract the numerators and keep the denominator the same.
- Example: 2/3 - 1/3 = 1/3
Multiplying Fractions
- To multiply fractions, multiply the numerators and multiply the denominators.
- Example: 1/2 × 1/3 = 1/6
- Multiplying a fraction by a whole number is the same as multiplying the numerator by the whole number.
- Example: 1/2 × 3 = 3/2
Dividing Fractions
- To divide fractions, invert the second fraction (i.e., flip the numerator and denominator) and then multiply.
- Example: 1/2 ÷ 1/3 = 1/2 × 3/1 = 3/2
- Dividing a fraction by a whole number is the same as dividing the numerator by the whole number.
- Example: 1/2 ÷ 3 = 1/6
