(a)
316223 = 300000 + _____ + 200 + 23
316223 = 300000 + _____ + 223
316223 - 300000 - 223 = 16000
(b)
445824 = _____ + 40000 + 5000 + 800 + 20 + 4
445824 = _____ + 45824
445824 - 45824 = 400000
(c)
188984 = 100000 + 80000 + _____ + 900 + 80 + 4
188984 = 180000 + _____ + 984
188984 - 180000 - 984 = 8000
(d)
248618 = 200000 + 40000 + 8000 + _____ + 10 + 8
248618 = 248000 + _____ + 18
248618 - 248000 - 18 = 600
