Study Notes
Understanding Operations with Fractions
- Fractions are numerical values that express parts of a whole
- Addition of fractions requires finding a common denominator and adding the numerators
- Subtraction of fractions also requires a common denominator and subtracting the numerators
- Multiplication of fractions involves multiplying the numerators and denominators separately
- Division of fractions involves multiplying one fraction by the reciprocal of the other fraction
- To add fractions, first find a common denominator, then add the numerators and leave the denominator unchanged
- To subtract fractions, find a common denominator, subtract the numerators, and leave the denominator unchanged
- To multiply fractions, multiply the numerators and denominators separately, and write the new numerator over the new denominator
- To divide fractions, write the first fraction beside the reciprocal of the second fraction, multiply the numerators, and multiply the denominators
- Follow specific steps for each operation: adding, subtracting, multiplying, and dividing fractions
- Example problems and step-by-step solutions are provided for each operation
