To calculate a fraction, follow these steps: Determine the numerator (top number) and denominator (bottom number). For simple division, divide the numerator by the denominator. To add or subtract fractions, make sure they have the same denominator, adjust if necessary, then perform the operation on the numerators. Multiply fractions by multiplying numerators and denominators across. For division, multiply by the reciprocal of the second fraction. Always simplify your results by dividing the numerator and denominator by their greatest common factor for the simplest form.
FAQs & Answers
- How do I simplify a fraction? To simplify a fraction, divide both the numerator and the denominator by their greatest common factor (GCF) until no further simplification is possible.
- What do I do if the fractions have different denominators? If the fractions have different denominators, find a common denominator by determining the least common multiple (LCM) of the denominators, then adjust the fractions before performing addition or subtraction.
- Can fractions be converted to decimals? Yes, fractions can be converted to decimals by dividing the numerator by the denominator. For example, 1/2 equals 0.5.
- What is the reciprocal of a fraction? The reciprocal of a fraction is obtained by swapping its numerator and denominator. For instance, the reciprocal of 3/4 is 4/3.
