- 1. Equivalent Fractions Mrs. Emeott's 4th Grade Class Clare Primary School
- 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. 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.
- 5. Fraction Models: So 2/3 is the same as 8/12.
- 6. One Whole One Whole
- 7. Cut Them inHalf 1 The Numerator 2 The Denominator (How many pieces its cut into)
- 8. Cut them inHalf 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. They are theSame! One Half is equivalent to 2 quarters. 1 2 2 = 4
- 10. Why use EquivalentFractions? Equivalent Fractions make large numbers easier to deal with. Smaller numbers are simple. 50 5 1 100 = 10 = 2
- 11. To Find EquivalentFractions: Multiply the numerator and denominator by the same number. 1 4 4 5 x 4 = 20
- 12. To Find EquivalentFractions Multiply the numerator and denominator by the same number. 15 Divide by 3 45 Divide by 3 Both 15 and 45 have 3as a common factor!
- 13. Find Equivalent Fractions 15 Divide by 3 5 45 = Divide by 3 15 Start thinking ahead. Can we make the 5/15 smaller? What number do 5 and 15 have in common?
- 14. 5 and 15have the number ____ in common! a. 3 b. 2 c. 5 d. 15
- 15. That's Correct! 5 and15 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. That's Incorrect. Sorry that's not right but don't 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. Now you tryit! 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. Click on thecorrect answer. 3/4 is equal to... a. 4/8 b. 6/8 c. 8/8 d. 3/8
- 19. That's Correct! 6/8 is the equivalent fraction to 3/4! 3 x2 6 4 x2 = 8
- 20. That's Incorrect! 6/8 is the equivalent fraction to 3/4! 3 x2 6 4 x2 = 8
- 21. Did you getthe right answer? 6, That's Right! 6/8 = 3/4 6 divided by 2=3 8 divided by 2= 4
- 22. Find the EquivalentFraction: 2 x3 5 x3 = ? a. 6/15 b. 3/12 c. 2/3 d. 1/10
- 23. That's Correct! 2 x3 6 5 x 3 = 15
- 24. That's Incorrect. 2 x3 6 5 x 3 = 15
- 25. Find the EquivalentFraction: 3 ? 8 = 56 a. 6/56 b. 18/56 c. 3/56 d. 21/56
- 26. That's Correct! 3 x7 21 8 x7 = 56
- 27. That's Incorrect. 3 x7 21 8 x7 = 56
- 28. What's the EquivalentFraction? What is the equivalent fraction to ½ (There is a HINT in the picture). a. 2/4 b.1/4 c. 2/2 d. 3/4
- 29. That is Correct! Theequivalent fraction to 1/2 is 2/4. 1 x 2= 2 2 x 2= 4
- 30. That's Incorrect. The equivalentfraction to 1/2 is 2/4. 1 x 2= 2 2 x 2= 4
- 31. Try your handat these bonus problems! 1) Find the Equivalent Fraction to 6/9. a. 3/9 b. 12/18 c. 6/18 d. 2/3
