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!
Given:
Mrs Johnson baked 2 dozen cookies.
[tex]\texttt{Total Number of Cookies} = 2 \times 12 = \boxed {24 ~ \texttt{cookies}}[/tex]
Two thirds of the cookies were oatmeal.
[tex]\texttt{Number of Oatmeal Cookies} = \frac{2}{3} \times \texttt{Total Number of Cookies}[/tex]
[tex]\texttt{Number of Oatmeal Cookies} = \frac{2}{3} \times 24[/tex]
[tex]\texttt{Number of Oatmeal Cookies} = \frac{2 \times 24}{3}[/tex]
[tex]\texttt{Number of Oatmeal Cookies} = \frac{48}{3}[/tex]
[tex]\texttt{Number of Oatmeal Cookies} = \boxed {16 ~ \texttt{cookies}}[/tex]
Proof:
[tex]\frac{\texttt{Number of Oatmeal Cookies}}{\texttt{Total Number of Cookies}} = \frac{16}{24} = \frac{16 \div 8}{24 \div 8} = \frac {2}{3}[/tex]
Conclusion :
