...Bob will give 1/4 of her 36 Cookies to her family, 1/9 to her friends, and will bring 2/3 of the cookies to school.
How many cookies will she give to her family? 1/4 of 36 is the same as 36/4 = ?
How many cookies will she give to her friend? 1/9 of 36 is the same as 36/9 = ?
and if he does both of the above, he will not have enough left to bring 2/3 of the 36 cookies to school. Why?
