Answer :

To transform it into percent we want to have 100 into denominator. The easiest way is divide numerator and denominator by 3 (thats because than it doesnt change the value of fraction), so:
[tex] \frac{258}{300}= \frac{258:3}{300:3}= \frac{86}{100} = 86% [/tex] - its the result

[tex]\\\\\frac{\big{43}}{\big{50}} =\frac{\big{43}}{\big{50}} \cdot 100\%=\frac{\big{43}}{\big{50}} \cdot 50\cdot2\%=43\cdot2\%=86\%[/tex]
