we need to find the greatest common factor (GCF) of 64 and 88. The GCF of 64 and 88 is 8, because 8 is the largest number that divides evenly into both 64 and 88.
If Leslie puts the greatest number of cookies in each snack bag, she will be able to put 8 cookies in each snack bag. To find the number of snack bags containing peanut butter cookies, we can divide the number of peanut butter cookies by the number of cookies in each snack bag:
88 peanut butter cookies / 8 cookies per snack bag = 11 snack bags containing peanut butter cookies
Therefore, 11 snack bags will contain peanut butter cookies if Leslie puts the greatest number of cookies in each snack bag.
