The sentence contains misplaced modifier.
According to the sentence, the one got hit by the car was Gunther. However, putting "I" as the subject of this sentence means that "I" was the one got hit. ("Having just been hit by a car" and "rushed over..." were done by the same person - "I")
So that, this sentence should be corrected, the following is an example:
<em>"Gunther had just been hit by a car, I rushed over to see if he was breathing."</em>
Well you could solve by cross multiplying 66 and 2/3 (into an improper fraction) multiplied by the reciprocal of 30, but 66 and 2/3 means 2/3 (1/3 equals 33 1/3 %) so then you can divide 30 by 3, which is 10, and then multiply by 2 to get 20. So, 66 and 2/3 of 30 is 20. Hope that helped!
It’s either b or C! I hope that all helps
