(a)
717313 = 700000 + _____ + 300 + 13
717313 = 700000 + _____ + 313
717313 - 700000 - 313 = 17000
(b)
174686 = _____ + 70000 + 4000 + 600 + 80 + 6

174686 - 74686 = 100000
(c)
441794 = 400000 + 40000 + _____ + 700 + 90 + 4
441794 = 440000 + _____ + 794
441794 - 440000 - 794 = 1000
(d)
797452 = 700000 + 90000 + 7000 + _____ + 50 + 2
797452 = 797000 + _____ + 52
797452 - 797000 - 52 = 400
