Answer 1

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 :

1. Parentheses
2. Exponents
3. Multiplication and Division
4. 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:

$\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times \texttt{Total number of Cookies}$

$\texttt{Number of Chocolate Cookies} = \frac{2}{3} \times 18$

$\texttt{Number of Chocolate Cookies} = 2 \times 6$

$\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}$

Conclusion :

$\texttt{Number of Chocolate Cookies} = 12 ~ \texttt{cookies}$

$\texttt{Number of Other Cookies} = (18 - 12) = 6 ~ \texttt{cookies}$
