Solving Method: Multiplication and Division Rules
Answer:
a) 18 x 10 = 180
82 x 100 = 8200
256 x 1000 = 256000
18 x 100 = 1800
75 x 1000 = 75000
302 x 10 = 3020
18 x 1000 = 18000
19 x 10 = 190
400 x 100= 40000
b) 9000 : 10 = 900
6800 : 100 = 68
20020 : 10 = 2002
9000 : 100 = 90
420 : 10 =42
200200 : 100 = 2002
9000 : 1000 = 9
2000 : 1000 = 2
2002000 : 1000 = 2002
