  1. 0.08
  2. 0.8
  3. 8
  4. 80
Explanation
Answer: C - A percentage is a way of expressing a fraction whose denominator is 100.
10.4/130 = 0.08 = 8/100 = 8%
Key takeaway: Percent literally means “per 100” or “out of 100”. Memories some common percentage-decimal-fraction equivalents, such as 0.01 = 1/ 100 = 1%, 0.1 = 1/10 = 10%, 1/ 4 = 25% = 0.25, 1/8 = 12.5% = 0.125
