(a)
451872 = 400000 + _____ + 800 + 72
451872 = 400000 + _____ + 872
451872 - 400000 - 872 = 51000
(b)
355773 = _____ + 50000 + 5000 + 700 + 70 + 3

355773 - 55773 = 300000
(c)
259594 = 200000 + 50000 + _____ + 500 + 90 + 4
259594 = 250000 + _____ + 594
259594 - 250000 - 594 = 9000
(d)
961721 = 900000 + 60000 + 1000 + _____ + 20 + 1
961721 = 961000 + _____ + 21
961721 - 961000 - 21 = 700
