Question

How would I solve this problem???

What is the product of 2.4 • 103 and 1.5 • 103? (1 point)

3.6 • 106
3.9 • 106
3.6 • 109
3.9 • 109

Answer 1

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

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
