Number of chocolate cookies is 12 cookies
Number of other cookies is 6 cookies
Further explanation
Order of Operations in Mathematics follow this following rule :
- Parentheses
- Exponents
- Multiplication and Division
- Addition and Subtraction
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 !
Given:
Out of 18 cookies, 2/3 are chocolate chip.
The above statement can be written in a mathematical equation as follows:
[tex]\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times \texttt{Total number of Cookies}[/tex]
[tex]\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times 18[/tex]
[tex]\texttt{Number of Chocolate Cookies} = 2 \times 6[/tex]
[tex]\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}[/tex]
Conclusion :
[tex]\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}[/tex]
[tex]\texttt{Number of Other Cookies} = (18 - 12) = 6 ~ \texttt{cookies}[/tex]
