  3. Lesson - Adding and Subtracting Fractions with common denominator Steps: • Make sure the fractions have the same denominator. • Add the numerators together. • Leave the denominator the same. Example: Click Here to Return to Menu

  4. Lesson – Generating Equivalent Fractions Steps: • Multiply the numerator and the denominator by the same number. • By doing so, you will create an equivalent fraction. Example1: 1 Whole ½ 2/4 3/6 4/8 Click Here to Return to Menu

  5. Lesson – Finding the Least Common Multiple (LCM) Steps: • Write out the multiples of the first number. • Write out the multiples of the second number. • Find the smallest multiple that both numbers have in common. Example: 4: 4, 8, 12, 16, 20, 24 5: 5, 10, 15, 20 LCM: 20 Example: 2: 2, 4, 6, 8, 10, 12, 14, 16 8:8 LCM: 8 Click Here to Return to Menu

  6. Lesson - Adding Fractions with Unlike Denominators Step: • Determine the denominators • Find the least common multiple (LCM). • Your least common multiple will become your least common denominator (LCD). • Generate Equivalent Fractions using the LCM as the LCD. • Add or Subtract Fractions. Example: 1. LCM: 3: 2, 4, 6, 8, 10, 12 4: 4, 8, 12 NEXT Click Here

  7. Lesson - Subtracting Fractions with Unlike Denominators Step: • Determine the denominators • Find the least common multiple (LCM). • Your least common multiple will become your least common denominator (LCD). • Generate Equivalent Fractions using the LCM as the LCD. • Add or Subtract Fractions. Example: 1. LCM: 2: 2, 4, 6 4: 4 Click Here to Return to Menu
