  1. Adding Fractions
    There are 3 Simple Steps to add fractions: Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put the answer over the denominator. Step 3: Simplify the fraction (if needed)
  2. Subtracting Fractions
    If two fractions have the same denominator you compute their difference by subtractingthe numerators. If the fractions have unlike denominators first rewrite the fractionsover a common denominator. Then compute the difference by subtracting the numerators,putting the answer over the common denominator, and reducing to lowest terms.
  3. Multiplying Fraction
    To multiply fractions, first we simplify the fractions if they are not in lowest terms. Then we multiply the numerators of the fractions to get the new numerator, and multiply the denominators of the fractions to get the new denominator. Simplify the resulting fraction if possible.
  4. Dividing Fractions
    Multiply by the reciprocal of the divisor. Take the reciprocal of the divisor -- the number after the division sign ÷ . Divide 4 into 40, then multiply. The denominators must be the same.
