4. FOCUS QUESTION: What are equivalent fractions?
Copyright © 2013 Kelly Mott

5. Equivalent fractions are fractions that show the same amount, but have different numerators and denominators. 1 2 1 1 = 4 1 2 4 2 4

6. FOCUS QUESTION: How can I use multiplication to get an equivalent fraction?
Copyright © 2013 Kelly Mott

7. = 1 2 x x You can multiply to get equivalent fractions.
To get equal fractions, multiply the numerator and denominator by the same number. 1 x = 2 x

14. FOCUS QUESTION: How do you reduce fractions?
Copyright © 2013 Kelly Mott

15. When you reduce a fraction, you try to get it to the simplest form.
To get a fraction in simplest form, you must by the divide the numerator and denominator by the greatest common factor. 8 ÷ = ÷ 12

26. FOCUS QUESTION: How do we compare fractions with different denominators?
Copyright © 2013 Kelly Mott

27. There are two ways to compare fractions with different denominators.
Copyright © 2013 Kelly Mott

28. If fractions do not have the same denominators, we need to find a common multiple and multiply to get the bottoms the same. 2 3 4 8

46. Improper Fractions

48. To express a mixed number as an improper fraction,
multiply the whole number by the denominator and add the numerator.
Write this sum over the denominator.

49. 2
2 x 2 + 1 = = 2 2 2

50. 2

51. To express an improper fraction as a mixed number,
Divide the denominator into the numerator.
Subtract what was “used”
Write the remainder over the original denomiator

52. 2 2 3 2 = 3 3 -6 2

53. Express the mixed number as an improper fraction.= = 5

54. Express the mixed number as an improper fraction.= = 9
