(a)
224231 = 200000 + _____ + 200 + 31
224231 = 200000 + _____ + 231
224231 - 200000 - 231 = 24000
(b)
536172 = _____ + 30000 + 6000 + 100 + 70 + 2

536172 - 36172 = 500000
(c)
222392 = 200000 + 20000 + _____ + 300 + 90 + 2
222392 = 220000 + _____ + 392
222392 - 220000 - 392 = 2000
(d)
493126 = 400000 + 90000 + 3000 + _____ + 20 + 6
493126 = 493000 + _____ + 26
493126 - 493000 - 26 = 100
