Hey there! :D
Make this into a fraction.
6+18+26= 50
26 orange tiles.
[tex] \frac{26}{50} [/tex]
Divide both (the numerator and the denominator) by 2.
[tex] \frac{26/2}{50/2} = \frac{13}{25} [/tex]
However, the question must not have the fraction in it's simplied state. So, the best answer would be "C". I would make sure to simplify your fractions as often as possible though, because it is widely used on state testing and exams.
I hope this helps!
