(a)
483128 = 400000 + _____ + 100 + 28
483128 = 400000 + _____ + 128
483128 - 400000 - 128 = 83000
(b)
142393 = _____ + 40000 + 2000 + 300 + 90 + 3
142393 = _____ + 42393
142393 - 42393 = 100000
(c)
533279 = 500000 + 30000 + _____ + 200 + 70 + 9
533279 = 530000 + _____ + 279
533279 - 530000 - 279 = 3000
(d)
921495 = 900000 + 20000 + 1000 + _____ + 90 + 5
921495 = 921000 + _____ + 95
921495 - 921000 - 95 = 400
