Multiplying by whole 10’s and 100’s contiuned

a)
20 x 7 = 140.
10 x 2 x 7 = 140.
10 x 14 = 140
140 x 10 x 14 = 280


b)
20 x 5 = 100
100 x 2 x 5 = 1,000
10 x 1,000 = 10,000
10,000 x 10 = 100,00
c)
200 x 8 = 1,600
1,600 x 2 x 8 = 25,600
25,600 x 100 = 256,000
256,000 x 100 = 25600,000

d)
200 x 5 = 1,000
1,000 x 2 x 8 = 16,000
16,000 x 100 = 1600,000
1600,000 x 100 = 160,000
