(a)
275893 = 200000 + _____ + 800 + 93
275893 = 200000 + _____ + 893
275893 - 200000 - 893 = 75000
(b)
271648 = _____ + 70000 + 1000 + 600 + 40 + 8

271648 - 71648 = 200000
(c)
921621 = 900000 + 20000 + _____ + 600 + 20 + 1
921621 = 920000 + _____ + 621
921621 - 920000 - 621 = 1000
(d)
789664 = 700000 + 80000 + 9000 + _____ + 60 + 4
