  2. Multiple A product of that number and any nonzero whole number

  3. To find LCMaka Least Common Multiple • Looooonnnnng Way: List out the multiples until you find one in common. Ex: 4,5 • Efficient Way: Cake Method and multiply the numbers on the left and bottom Ex: 9,15

  4. Ex Find the LCM: 12, 15,18

  5. Ex Find the LCM of 8m², 14m⁴

  6. Ex Find the LCM of 25y², 15x

  7. Comparing Fractions with Like Denominators • Compare the numerators. • Example: Compare and Graph -4/9 and -2/9

  8. Comparing Fractions with Unlike Denominators • Find the LCD (Least common denominator) aka the LCM of the denominators • Compare the numerators Example: Compare 6/7 and 4/5 • Heart Method • Example: Compare ¾ and 7/10
