butter cookies. 1/6 of the cookies are iced sugar cookies. 3/8 of the cookies are chocolate chip cookies. The rest of the cookies are oatmeal cookies. How many cookies are oatmeal cookies?
To find the fraction of cookies that are oatmeal cookies, first determine the fraction of cookies that are either iced sugar cookies or chocolate chip cookies: 1/6 + 3/8 = 4/24 + 9/24 = 13/24
Then subtract this fraction from 1 to find the fraction of cookies that are oatmeal cookies: 1 - 13/24 = 11/24
Finally, convert this fraction to a whole number to find how many cookies are oatmeal cookies: 11/24 * 24 = <<11/24*24=11>>11. Answer: \boxed{11}.
To find the number of oatmeal cookies, we need to subtract the number of iced sugar cookies and chocolate chip cookies from the total number of butter cookies.
Let's assume the total number of butter cookies is x.
Since 1/6 of the cookies are iced sugar cookies, we can calculate the number of iced sugar cookies as follows:
Iced sugar cookies = (1/6) * x
Similarly, 3/8 of the cookies are chocolate chip cookies:
Chocolate chip cookies = (3/8) * x
To find the number of oatmeal cookies, we need to subtract the number of iced sugar cookies and chocolate chip cookies from the total number of butter cookies:
Oatmeal cookies = Total number of butter cookies - (Iced sugar cookies + Chocolate chip cookies)
= x - [(1/6) * x + (3/8) * x]
Now, we can simplify the expression for oatmeal cookies:
Oatmeal cookies = x - (1/6)x - (3/8)x
= x - (8/48)x - (18/48)x
= x - (26/48)x
= (48/48)x - (26/48)x
= (22/48)x
Therefore, the number of oatmeal cookies is given by (22/48) times the total number of butter cookies.
To determine the number of oatmeal cookies, we need to find the portion of the total cookies that are neither iced sugar cookies nor chocolate chip cookies.
First, let's calculate the combined fraction of the iced sugar and chocolate chip cookies. We add the fractions 1/6 and 3/8 together.
1/6 + 3/8
To find a common denominator, we multiply 6 by 8 and 8 by 6, resulting in:
8/48 + 18/48
Now that the fractions have the same denominator, we add the numerators:
8/48 + 18/48 = 26/48
Simplifying the fraction by dividing both the numerator and denominator by the greatest common factor, which is 2, we get:
26/48 = 13/24
So, 13/24 of the cookies are either iced sugar cookies or chocolate chip cookies.
To determine the fraction of the cookies that are oatmeal cookies, we subtract this fraction from 1 (since the remaining fraction represents the oatmeal cookies):
1 - 13/24 = 11/24
Therefore, 11/24 of the cookies are oatmeal cookies.
To find the exact number of oatmeal cookies, you would need to know the total number of cookies.
