Explanation:
Convert each fraction by setting up proportion out of 100.
![(60)/(90) = (?)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/jk4sm91q8jj2lp5ndu6mrkivbyotsfew9a.png)
![(78)/(150) = (?)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/bwzcwg6k1nbv0kxdd0lmk1zxrwdjxitkoz.png)
![(75)/(120) = (x)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/lgncdpjs5hxl6hro3ruw9n3zt2lz3m7f6d.png)
Cross multiply each fraction. let x represent the missing number.
![6000 = 90x](https://img.qammunity.org/2022/formulas/mathematics/high-school/3a3ct1vxvr1hzift9m8doo03x9penp1fq2.png)
![7800 = 150x](https://img.qammunity.org/2022/formulas/mathematics/high-school/w4rjjkvhgjjnq5a5lnya4qindpqgafn0zu.png)
![7500 = 120x](https://img.qammunity.org/2022/formulas/mathematics/high-school/o0cuvkfhp1mg59e7msu821r2xhsrfgup0o.png)
Solve for x
For the first equation.
![x = 66.66666](https://img.qammunity.org/2022/formulas/mathematics/high-school/n5s9r2mqh0co91ppbp0eeoiq10b4i5dx5v.png)
For the second equation
![x = 52](https://img.qammunity.org/2022/formulas/mathematics/high-school/3eoyo3ybtggp8e8dsjczh3i85dsz7r9e3b.png)
For the third equation,
![x = 62.5](https://img.qammunity.org/2022/formulas/mathematics/high-school/oakac6ly84zccf7vlwb72v4qjmtrzlxds6.png)
Round each missing value to the nearest whole value and add the % sign.
60/90=67%
78/150=52%
75/120=63%
