When multiplying or dividing numbers containing decimals by 10, 100, 1000, etc., there's no need for long division or multiplication. You need only MOVE the decimal place.

This is working hard, not smart.
D.L.M.R tells us that when we divide by 10, 100,
1000, etc., we move the decimal
left
and when we multiply, we move the decimal
right
We move one place for every zero (0) in the 10, 100, 1000, 10,000, etc.
In the example above, we are multiplying by 100. There are 2 zeroes. We need to move the decimal 2 places to the...............................................right.
The answer is 272.
More examples, covering some trickier problems, will follow in the next postings.
