12.45*10=</span><span>124.5*10 Moving to the right (1 "step")
37.321*100=3732.1 </span><span>Moving to the right (2 "steps")
1.56789*1000=15678.9 </span> <span>Moving to the right (3 "steps")
2) D</span>ividing (for 10 , 100, 1000 <span>always moving to the left)
56.89/10= 5.689 </span>Moving to the left (1 "step")<span>
234.98/100=2.3498 </span>Moving to the left (2 "steps")<span>
78956.67/1000=78.95667 </span><span>Moving to the left (3 "steps")</span><span>
