Explanation:
Ratios and Fractions
It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:
![1 - (1)/(5)=(4)/(5)](https://img.qammunity.org/2022/formulas/mathematics/high-school/waeuwfx23123fgiularnjca9x23ngjzolm.png)
We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.
This can be done by dividing 1/5 by 4/5:
![\displaystyle ((1)/(5))/((4)/(5))](https://img.qammunity.org/2022/formulas/mathematics/high-school/r5fkzql8b3o65a9vmnowmbfkts4x6vquu4.png)
Operating:
![\displaystyle (1)/(5)\cdot(5)/(4)=(1)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/abrbtig4aa53kv4oh8qdp2uyrl1oyvdh0i.png)
Expressing it as a ratio: 1:4
