  47 x 10 = 470
    8 x 10 = 80
 3528 x 10 = 35280
12123 x 10 = 121230
4100 x 10 = 41000

b)

245 x 100 = 24500
300 x 100 = 30000

c) 
7 x 1000 = 7000
21 x 1000 = 21000
212 x 1000 = 212000
220 x 1000 = 220000
6 x 1000 = 6000.

Answer 2

a)1250=125*10, 470=47*10, 80=8*10,121230=12123*10,41000=4100*10

b) 4000=40*100, 500=5*100, 13700=137*100,24500=245*100,30000=300*100

c) 7000=7*1000,21000=21*1000,212000=212*1000,22000=22*1000,6000=6*1000
