    Answer:

    The 3 digit number 642 when multiplied 97 gives the greater product.

    Step-by-step explanation:

    The greatest product will result by multiplying the smaller 3 digit number with the greater two digit number.

    The greater three digit number will be 976 and smaller 2 digit number would be 42

    Multiplying

    976*42 = 40992   ( descending order number)

    679 *24= 16,296  ( ascending order number)

    If we take the 2 digit number as 97 and  3digit number 642

    Then multiplying

    642* 97= 62,274  ( descending order  number)

    246 * 79=19434   ( ascending order number)

    The 3 digit number 642 when multiplied 97 gives the greater product.
