100 (30,000/21,000) = 142.85 %, if all the zeros in the data are significant.
30
To solve, move your decimal place 30 spots to the right: 1.9*10^30 = 1900,000 000 000 000 000 000 000 000 000

21/30 x 100% = 70%
To work out the percentage of, for example, 21 correct answers out of 30 questions, do the following: 21 ÷ 30 × 100 = 70 (add the percentage sign, thus: 70%)(If the answer had been 0.70, ignore the 0. and use 70 as the percentage.)
70%
Expressed as a percentage, 21/70 x 100 = 30 percent.
A percentage is 'parts per hundred' and there are possibly 100 of them. ppm is parts per million. There are 10 000 hundreds in a million. So multiply your percentage by 10 000. i.e. 3% x 10 000 = 30 000 ppm. but check my math.
Expressed as a percentage, 21/70 x 100 = 30 percent.
35.2941% difference.

30 - 9 = 21 kids didn't. (21/30)*100 = 70% didn't get an A (meaning 30% did)
