Peanut butter are ³/₈ of all the cookies
Further explanation
Order of Operations in Mathematics follow this following rule :
- Multiplication and Division
This rule is known as the PEMDAS method.
In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
Let us tackle the problem!
Let :
Total Number of Cookies = X
Given:
¹/₄ of the cookies are chocolate chip
\(\texttt{Chocolate Chip Cookies} = \frac{1}{4} \times \texttt{Total Number of Cookies}\)
\(\texttt{Chocolate Chip Cookies} = \frac{1}{4} \times X\)
\(\texttt{Chocolate Chip Cookies} = \boxed {\frac{1}{4} X}\)
Let's find the fraction for other cookies
\(\texttt{Other Cookies} = \texttt{Total Number of Cookies} - \texttt{Chocolate Chip Cookies}\)
\(\texttt{Other Cookies} = X - \frac{1}{4} X\)
\(\texttt{Other Cookies} = \frac{4}{4}X - \frac{1}{4} X\)
\(\texttt{Other Cookies} = \frac{4 - 1}{4}X\)
\(\texttt{Other Cookies} = \boxed {\frac{3}{4}X}\)
¹/₂ of the rest are peanut butter
\(\texttt{Peanut Butter Cookies} = \frac{1}{2} \times \texttt{Other Cookies}\)
\(\texttt{Peanut Butter Cookies} = \frac{1}{2} \times \frac{3}{4}X\)
\(\texttt{Peanut Butter Cookies} = \frac{1 \times 3}{2 \times 4}X\)
\(\texttt{Peanut Butter Cookies} = \boxed {\frac{3}{8}X}\)
