(a)
246590 = 200000 + _____ + 500 + 90
246590 = 200000 + _____ + 590
246590 - 200000 - 590 = 46000
(b)
812886 = _____ + 10000 + 2000 + 800 + 80 + 6
812886 = _____ + 12886
812886 - 12886 = 800000
(c)
216859 = 200000 + 10000 + _____ + 800 + 50 + 9
216859 = 210000 + _____ + 859
216859 - 210000 - 859 = 6000
(d)
363471 = 300000 + 60000 + 3000 + _____ + 70 + 1
363471 = 363000 + _____ + 71
363471 - 363000 - 71 = 400
