Answer:
Is there supposed to be a fraction on the 4??
Step-by-step explanation:
Yes you did those two correctly
As fraction it would be 6/30 reduced 1/5 and as percentage 20% so 20% of the students were off.<span />
<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>
