Answer:
2.4 *103 = 247.2
1.5*103 = 154.5
3.6*106 = 381.6
3.9*106 = 413.4
3.6*109 = 392.4
3.9*109 = 425.1
Step-by-step explanation:
2.4 * 103
we firstly count decimal numbers
in the calculation
only 2.4 has a decimal and only one number after the point
so we keep it aside making
2.4 = 24 1 dp (decimal place)
back to the calculation
1 0 3
* 2 4
----------
4 1 2
2 0 6
-------------
2 4 7 2
-------------
don't forget we still have a dp !
so we place the point 1 step backward
2472 to 1dp =
247.2
with this we can solve orders
