3) http://www.helpwithfractions.com/equivalent-fractions.html
this math site it shows you how to make equivalent fractions and making them into lowest terms. This site gives an "Equivalent Fractions Table" which is uhmm interesting and helpful.?


4) a. One of my friends had 3/4 of a chocolate bar left and my other friend had 2/3 left of a chocolate bar, they decided to put their chocolate together and share it but before they divide it how muuch chocolate do they have all together?

  • 4) a. One of my friends had 3/4 of a chocolate bar left and my other friend had 2/3 left of a chocolate bar, they decided to put their chocolate together and share it but before they divide it how muuch chocolate do they have all together?

    3/4 + 2/3 (find LCD)

    so 9/12 + 8/12 = 17/12

    your friends had 17/12 of chocolate all together

    ===================================

    2 3/5 - 1 1/3 (again.. find LCD)

    It's 15

    so 2 9/15 - 1 5/15 = 1 4/15

    your friend is left with 1 4/15

  • 4) a. One of my friends had 3/4 of a chocolate bar left and my other friend had 2/3 left of a chocolate bar, they decided to put their chocolate together and share it but before they divide it how muuch chocolate do they have all together?

    The LCD is 12.
    So 3/4 becomes 9/12 cause:
    3 X 3 = 9
    4 X 3 = 12
    2/3 becomes 8/12 cause:
    2 X 4 = 8
    3 X 4 = 12

    Add 9/12 and 8/12 together to get 17/12.
    Your friends have 17/12 of chocolate altogether.

    b. Once again my friend had more chocolate bars, this time she had 2 3/5 chocolate bars left and another friend got hungry and took 1 1/3 chocolate bars from her portion. how much chocolate bars is my friend left with?

    Find the LCD which is 15.
    3/5 becomes:
    3 X 3 = 9
    5 X 3 = 15

    1/3 becomes:
    1 X 5 = 5
    3 X 5 = 15

    Add Subtract them: 2 9/15 - 1 5/15
    Your friend is left with 1 4/15 of chocolate.

    2/3 + 3/4
    8/12 + 9/12 = 17/12
    LCD = 12

    altogether your friends had 17/12 of chocolate.

    b. Once again my friend had more chocolate bars, this time she had 2 3/5 chocolate bars left and another friend got hungry and took 1 1/3 chocolate bars from her portion. how much chocolate bars is my friend left with?

    2 3/5 - 1 1/3
    2 9/15 - 1 5/15 = 1 4/5
    LCD = 15

    your friend had 1 4/5 left of chocolate.

    3/4 + 2/3 = ?

    • First you have to find the lowest common denominator or LCD which is 12

    • So it becomes 9/12 + 8/12 = ?

    • 9 + 12 = 17

    • So it is 17/12

    • Your friends had 17/12 of chocolate when they put theirs together.
