  1. 1. Equivalent Fractions Mrs. Emeotts 4th Grade Class Clare Primary School
  2. 2. Table of Contents:  What is an Equivalent Fraction? Why use Equivalent Fractions?  How to find Equivalent Fractions? Now you try to find Equivalent Fractions
  3. 3. Equivalent Fractions  Equivalent means “Equal” The numerator (top number) is different  The denominator (bottom number) is different. Although they are different numbers they are the same amount.
  4. 4. Fraction Models:
  5. 5. Fraction Models: So 2/3 is the same as 8/12.
  6. 6. One Whole One Whole
  7. 7. Cut Them in Half 1 The Numerator 2 The Denominator (How many pieces its cut into)
  8. 8. Cut them in Half Again I still show the same thing, but now I also show a new fraction that is equal (equivalent) 1 And Also 2 2 4
  9. 9. They are the Same! One Half is equivalent to 2 quarters.1 22 = 4
  10. 10. Why use Equivalent Fractions? Equivalent Fractions make large numbers easier to deal with. Smaller numbers are simple.50 5 1100 = 10 = 2
  11. 11. To Find Equivalent Fractions: Multiply the numerator and denominator by the same number. 1 4 4 5 x 4 = 20
  12. 12. To Find Equivalent FractionsMultiply the numerator and denominator by the same number.15 Divide by 345 Divide by 3Both 15 and 45 have 3as a common factor!
  13. 13. Find Equivalent Fractions 15 Divide by 3 5 45 = Divide by 3 15Start thinking ahead. Can we make the5/15 smaller? What number do 5 and 15 have in common?
  14. 14. 5 and 15 have the number ____ in common!a. 3b. 2c. 5d. 15
  15. 15. Thats Correct!5 and 15 both have the number 5 in common!So 5/15 can be made smaller by dividing the top and bottom numbers by 5! 5 1 15 = 3
  16. 16. Thats Incorrect. Sorry thats not right but dont give up!!!5 and 15 both have the number 5 in common!So 5/15 can be made smaller by dividing the top and bottom numbers by 5! 5 1 15 = 3
  17. 17. Now you try it!Look at the top picture. It is cut into fourths.The bottom picture is cut into eighths. How many eighths would be equal to the the ¾ that are shaded red?
  18. 18. Click on the correct answer.3/4 is equal to...a. 4/8b. 6/8c. 8/8d. 3/8
  19. 19. Thats Correct! 6/8 is the equivalent fraction to 3/4!3 x2 64 x2 = 8
  20. 20. Thats Incorrect! 6/8 is the equivalent fraction to 3/4!3 x2 64 x2 = 8
  21. 21. Did you get the right answer?6, Thats Right!6/8 = 3/46 divided by 2=38 divided by 2= 4
  22. 22. Find the Equivalent Fraction: 2 x3 5 x3 = ?a. 6/15b. 3/12c. 2/3d. 1/10
  23. 23. Thats Correct!2 x3 65 x 3 = 15
  24. 24. Thats Incorrect.2 x3 65 x 3 = 15
  25. 25. Find the Equivalent Fraction: 3 ? 8 = 56a. 6/56b. 18/56c. 3/56d. 21/56
  26. 26. Thats Correct!3 x7 218 x7 = 56
  27. 27. Thats Incorrect.3 x7 218 x7 = 56
  28. 28. Whats the Equivalent Fraction?What is the equivalent fraction to½ (There is a HINT in the picture).a. 2/4b.1/4c. 2/2d. 3/4
