- 129485 = 100000 + 20000 + 9000 + _____ + 80 + 5
(a)
247101 = 200000 + _____ + 100 + 1
247101 = 200000 + _____ + 101
247101 - 200000 - 101 = 47000
(b)
618124 = _____ + 10000 + 8000 + 100 + 20 + 4
618124 = _____ + 18124
618124 - 18124 = 600000
(c)
133823 = 100000 + 30000 + _____ + 800 + 20 + 3
133823 = 130000 + _____ + 823
133823 - 130000 - 823 = 3000
(d)
129485 = 100000 + 20000 + 9000 + _____ + 80 + 5
129485 = 129000 + _____ + 85
129485 - 129000 - 85 = 400
