Answer:
The decimal place will be placed to the left by the total number of digits after the two numbers.
Explanation:
The multiplication we are asked to perform is
[tex]1.35\times4.2[/tex]
which has a total of 3 digits after the decimal point.
Now we know that
[tex]135\times42=5670[/tex]
therefore, to find 1.35 x 4.2 we just shift the decimal place in the above to the left by 3 units
therefore
[tex]1.35\times4.2=5.67[/tex]
which is our answer!
