u know how deka and deci are on the metric scale?well wat if the question is convert 100 dm into (answer)Dm?
I assume you are using Dm for decameters. The correct abbr. is da.
Here is what I do.
kilo
hecto
deca
unit, meter, liter, second, etc
deci
centi
milli
Start at deci. We move up one place to the unit (in this case meter), and another place to da. So move the decimal point to the left two places (because we moved up two places). Move the decimal point the number of places you move to get from one place to another. Move to the left if you go up the table; move to the right if you down the table.
To convert 100 dm to decameters (da), you would need to move from decimeters (dm) to decameters (da), which means moving from the right to the left on the metric scale.
Since we are moving two places to the left (from deci to deca), we need to move the decimal point in 100 dm two places to the left as well.
So, let's take 100 dm and move the decimal point two places to the left:
100 dm = 1.00 da
Therefore, 100 dm is equivalent to 1.00 da.
