500 + 420 + 669944 + 154104 = 824968
500
500% of 420= 500% * 420= 5 * 420= 2,100
84% of 500 = 420
It is: 84%
6300
C = 100 and D = 500 but 400 is written as CD (100 less than 500) X is 10 and 20 is simply XX (10 + 10) so 420 would be CDXX
287 + 491 + 200 + 500 + 300 + 500 + 280 + 400 + 290 + 490 = 3738
1,620
500 + 500 = 1000
(((800 plus 400) plus 400) plus 500) plus 500 = 2600
500 x 0.84 = 420 percent. I hope this helps because I am only in year seven.
500 + 0 = 500
