Explanation:
Let x be the percentage then...
![x\%(4)=2](https://img.qammunity.org/2023/formulas/mathematics/college/5ofps95tzzxyhfaj7ik3v1r8si3z1dn3j3.png)
Start by dividing both sides by 4:
![x\%=(2)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/6se7zpyt4uqkcn3f3k9gpmmwue0dep1rh1.png)
Simplify the fraction:
![x\%=(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/qgv6jyyv8tudiky92307kht0tlidyo0mli.png)
Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.
![x\%=(1)/(2)*(50)/(50)\\x\%=(50)/(100)\\x=50\%](https://img.qammunity.org/2023/formulas/mathematics/college/js1jk0bi7ghoekhk057y1tdf09dxe11sj1.png)
