(a)
577498 = 500000 + _____ + 400 + 98
577498 = 500000 + _____ + 498
577498 - 500000 - 498 = 77000
(b)
811271 = _____ + 10000 + 1000 + 200 + 70 + 1
811271 = _____ + 11271
811271 - 11271 = 800000
(c)
336284 = 300000 + 30000 + _____ + 200 + 80 + 4
336284 = 330000 + _____ + 284
336284 - 330000 - 284 = 6000
(d)
428893 = 400000 + 20000 + 8000 + _____ + 90 + 3
428893 = 428000 + _____ + 93
428893 - 428000 - 93 = 800
