Answer:
1/12
Explanation:
It is given that :
Amount of cereal left = 1/3 of a box
Number of people amongst whom the box of cereal is to be divided equally = 4
Therefore, an equation representing this problem is :
![$(1/3)/(4) = x$](https://img.qammunity.org/2022/formulas/mathematics/high-school/v0n3trchh316x4haqmqvj74fypb7fqatsl.png)
where x = is the amount of the share each brother gets.
Therefore solving the equation, we get :
![$(1/3)/(4) = x$](https://img.qammunity.org/2022/formulas/mathematics/high-school/v0n3trchh316x4haqmqvj74fypb7fqatsl.png)
![$(1)/(3) * (1)/(4) = x$](https://img.qammunity.org/2022/formulas/mathematics/high-school/kv8w9t7q3kuxgoi2p3fayfyuvnn2r0408k.png)
![$(1)/(12)=x$](https://img.qammunity.org/2022/formulas/mathematics/high-school/ejbxx706s4ng1dqr7b1wp86p7dcwrb7sxw.png)
So, each brother got 1/12th of the cereal left.
