how to you compare 8 fractions with different denominators including improper fractions?

  • math -

    Either change them to equivalent decimals or to fractions with the same denominators.

  • math -

    1. make them the same denominator, or
    2. find the decimal equivalents for each.

  • math -

    how do you change them into equivalent decimals and same denominators?

  • math -

    For decimals, divide the numerator by the denominator.

    Example: 3/4 = 0.75

    For fractions, find a common multiple of the denominators.

    Examples: 2, 3, 4, >> the common multiple is 12.

  • math -

    so it's like you do this ->

    2,4,6,8,10,12
    3,6,9,12,15,18,21
    4,8,12,16,20

    and one more question, what about the numerators?

    like if you're comparing 3/8 to 2/5 the common multiple is 40. the numerators?

  • math -

    Divide the new denominator by the old denominator.

    40/5 = 8

    Multiply the old denominator by the quotient.

    2 * 8 = 16

    2/5 = 16/40

  • math -

    so it would be like, 5/8 ? 6/7

    8,16,24,32,40,48,56,64
    7,14,21,28,35,42,49,56

    LCD IS 56

    so now i do 56/7=8*6=48 6/7=48/56

    56/8=7*5=35 so, 5/8=35/56


    5/8 (35/56) < 6/7 (48/56)
