Multiplying fractions

  1. chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2024%20x%20%5Cfrac%2036&chs=66x66
    • Rule: when multiplying fractions just multiply the numerators and denominators straight across and simplify.you do not need a least common denominator( LCD)
    • Step 1:                          2 x 3 =6
    •           chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2024%20x%20%5Cfrac%2036&chs=66x66                     4 x 6 = 24         

    • Step 2:     (6 x 1)            simplifying
    • chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%206%7B24%7D&chs=38x66             (6 x 4)  

    FINAL ANSWER:  chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2014&chs=22x64

    Answer:  chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2014&chs=22x64
    • Another way of getting the same answer..
    • Step 1                       2 x 3 = 6
    • chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2024%20x%20%5Cfrac%2036&chs=66x66                          2  x 12 = 24

    • Step 2                         Simplify
    •                   (3 x 2)
    • chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%206%7B24%7D&chs=38x66              (3 x 8)      =     chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2028&chs=20x64

    • Step 3              Simplify some more..
    •                 (2 x 1)
    • chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2028&chs=20x64              ( 2 X 4)       = chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%2014&chs=22x64


    it took 2 steps to get the same answer!

    • Multiply numerators and denominators straight across.
    • in this example we did not need to simplify
    • chart?chf=bg,s,00000000&cht=tx&chl=%5Cfrac%20%7B10%7D%7B21&chs=32x64 is already simplified
    • meaning there is no number that can divide into 10 and 21 evenly
