Answer

Suggested Answer

The suggested answer is C.

Theres no need to calculate either quantity, and you can cancel the products from both columns. To make the comparison, observe the place-value shifts from the decimal number 9.3. In Column A, the decimal point shifts 3 places left (9,300) and 3 places right (.0093), so the quantity is equivalent to (9.3) (9.3). You can now see that Quantity B, which is (9.3)(9.3), is the same as Quantity A.
