Explanation:
Given
![Orna\ ments = 2](https://img.qammunity.org/2022/formulas/mathematics/high-school/mhlfhijbqprddjpznxdn4dky5oc11yks4r.png)
![Time = 4](https://img.qammunity.org/2022/formulas/mathematics/high-school/jqunbpikzu5g30rh2g7q8zruuin7zkeuoo.png)
Required
Determine the ornaments per hour
This question implies that we calculate the unit rate.
![Unit\ Rate = (Orna\ ments)/(Time)](https://img.qammunity.org/2022/formulas/mathematics/high-school/m460w9gw0zoo0w0u3insq1v1qm19hciwca.png)
Substitute values for Time and number of ornaments
![Unit\ Rate = (2)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/o763flj1c4mmvqodn8o7qp78c3y5l4ymcf.png)
![Unit\ Rate = (1)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/q6nknu3m2dn4cysxc269w8vl28k2phbw00.png)
This implies that Constance can decorate 1/2 ornaments in an hour
