Step-by-step 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:

$1 - \frac{1}{5}=\frac{4}{5}$

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:

$\displaystyle \frac{\frac{1}{5}}{\frac{4}{5}}$

Operating:

$\displaystyle \frac{1}{5}\cdot\frac{5}{4}=\frac{1}{4}$

Expressing it as a ratio: 1:4
