(a)
281585 = 200000 + _____ + 500 + 85
281585 = 200000 + _____ + 585
281585 - 200000 - 585 = 81000
(b)
363143 = _____ + 60000 + 3000 + 100 + 40 + 3
363143 = _____ + 63143
363143 - 63143 = 300000
(c)
624482 = 600000 + 20000 + _____ + 400 + 80 + 2
624482 = 620000 + _____ + 482
624482 - 620000 - 482 = 4000
(d)
638624 = 600000 + 30000 + 8000 + _____ + 20 + 4
638624 = 638000 + _____ + 24
638624 - 638000 - 24 = 600
