Answer:

8/12 ;; 66%

Step-by-step explanation:

If you have 4 questions, with each having 3 answers, then you have 12 options (the denominator). If one is correct for each answer, then the correct is 4/12. Then you have to find the remaining part to see what is wrong.

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

  • (\frac{2}{3}s + \frac{5}{6}s) = 21
  • (\frac{4}{6}s + \frac{5}{6}s) = 21
  • \frac{9}{6}s = 21
  • \frac{3}{2}s=21

Step 2: Multiply both sides by 2/3.

  • \frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}
  • s = \frac{42}{3}
  • s = 14
