  1. PROPORTION

  2. PROPORTION A proportion is a comparison between two ratios or fractions.

  3. PROPORTION A proportion is a comparison between two ratios or fractions.

  4. PROPORTION A proportion is a comparison between two ratios or fractions. Multiplied both numerator & denominator by “4” As you can see, you can either multiply by the same factor…

  5. PROPORTION A proportion is a comparison between two ratios or fractions. Divided both numerator & denominator by “4” As you can see, you can either multiply by the same factor… Or divide by the same factor…

  6. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor.

  7. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion

  8. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion What would you multiply 4 by to get 20 ?

  9. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion What would you multiply 4 by to get 20 ? Correct, 5

  10. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion What would you multiply 4 by to get 20 ? So if we multiply the denominator by 5…

  11. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion What would you multiply 4 by to get 20 ? So if we multiply the denominator by 5… We multiply the numerator by 5 …

  12. PROPORTION So when a piece of the proportion is missing, you can easily solve for the missing piece by either multiplying or dividing by the same factor. EXAMPLE : Complete the proportion What would you multiply 4 by to get 20 ? So if we multiply the denominator by 5… We multiply the numerator by 5 … And complete the proportion
