Answer 1

If we remove the decimal points, then we end up multiplying two whole numbers.  We get

 

68 × 8

 

 

We can easily multiply these numbers using long division.

 

 

  6

 

  68

×  8

_____

     4         ----> multiply the 8 by the 8.

 

 

 

  6

 

  68

×  8

____

 544           ----->  multiply the 6 by the 8.  Keep in mind the digit being carried in the tens place.

 

 

The product is 544 when we have whole numbers.  But, we have to consider the decimal points.  Both numbers have decimals one unit to the left of the ones place of the numbers.  So we need to move the decimal 2 places to the left from the ones place of the product.

 

6.8 × 0.8 = 5.44
