12.03×0.76=?

      12.03
     ×0.76
-------------
      7218
  +84210
---------
    914.28

The reason it's wrong is that the decimal place was placed incorrectly in the final result.

mathstudent55 · Answer

12.03×0.76=?

      12.03  ---> 2 decimal places
     ×0.76  ---> plus 2 decimal places = 4 decimal places
-------------
      7218
  +84210
---------
    9.1428 ---> this number needs to have 4 decimal places, not 2.
