Not exactly. 506x9 = 4554 and 507 x9 = 4563.
-4.561 = -4561/1000 = -4561/1000-4.561 = -4561/1000 = -4561/1000-4.561 = -4561/1000 = -4561/1000-4.561 = -4561/1000 = -4561/1000
5divided by9 = 0.5555555555555556
7 divided by9 = 0.7777777777777778
1subtracted by9 tenths = -8
68 divided by9 = 7.555555555555555
Every one of the infinite number of multiples of 9 is, as well as roughly 1/3 of the multiples of 3. There sure are a huge number of them.
