    A Fraction Question

    Hey,


    A bag contains counters that are RED, BLACK, or GREEN.

    "1 OVER 3" are red
    "1 OVER 6" are black

    There are 15 green counters in the bag. How many black counters are in the bag?

    I multiplied the "1 OVER 3" by 2 to get
    "2 OVER 6"

    So then its the same as the black ones, so green must be:
    "3 OVER 6"

    And so..Im not sure how what to do from here...

    Thanks

    Hello,

    A bag contains counters that are RED, BLACK, or GREEN.

    "1 OVER 3" are red
    "1 OVER 6" are black

    There are 15 green counters in the bag. How many black counters are in the bag?

    I multiplied the "1 OVER 3" by 2 to get
    "2 OVER 6"

    So then its the same as the black ones, so green must be:
    "3 OVER 6"
    Correct until this point

    You know that 3/6 of the counters are green, that is 3/6 of the counters make 15 counters.

    So 1/6 of the counters, which are black, will make (15/3)=5 counters, since 1/6 is one third of 3/6.
