Fill in the blanks:

The product using the general rule for 9250 x 29= [[1]].

The general rule says, round off each factor to its greatest place, then multiply the rounded-off factors.

So,

9,250 is rounding off to the nearest thousands ⇒ 9,000 and 

29 is rounding off to the nearest tens ⇒ 30.

Then the product is 9,000  x 30 = 2,70,000.
