Answer:
1:3
Step-by-step explanation:
The part that contains nuts = 1/4
The part that do not contain nuts = 1-1/4 =3/4
We need to find the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts. It can be calculated as follows :
[tex]Ratio=\dfrac{\dfrac{1}{4}}{\dfrac{3}{4}}\\\\=\dfrac{1}{4}\times \dfrac{4}{3}\\\\=\dfrac{1}{3}[/tex]
So, the required ratio is 1:3.
