    How many batches of 11 cookies are there in 132 cookies? 12 batches of 11 cookies. So, what is 2/3 times 12? 24/3, which is equal to 8/1, which is equal to 8 cups of milk. You will need 8 cups of milk for 132 cookies.

    132 / 11 = 12 batches

    12 times 2/3 = (12 x 2) / 3 = 24 / 3 = 8 cups of milk.

    The answer is 8

    You need 2/3 cup of milk for 11 cookies. Well, you want to make 132, right?

    To find out, divide 132 by 11. You get 12. That's how many batches of 11 cookies you'll have. Since every batch requires 2/3 cup of milk, and you have 11 batches, just multiply 2/3 by 12

    11 cookies -> 2/3 of a cup of milk

    132 cookies --> (2/3) * (1/11) * 132 = 8 cup of milk

    Divide 132 by 11 and multiply by 2/3:

    132 / 11 = 12

    12 * 2 / 3 = 24 / 3 = 8

    8 cups

    (b)

    Answer is b

    That means that you need (2/3)/11 of a cup for each cookie, or 2/33 cups.

    now (2/33) x 132 = 2x132/33 = 8

    direct variation---the more cookies you make the more milk needed. therefore the ratios are equal

    let x be the no. of cups of milk needed.

    (2/3)/11 = x/132

    11x = 88

    x = 8 cups of milk

    2/3*12=24/3=8

    Because it will take 12 batches of 11 to make 132
