To solve this problem of dividing 124 by 100, we apply the following procedure:
Hence, when we divide 124 by 100, the resulting number is .
\( \text{0}.07\times10= \)
Because 100 has two zeros! Each zero represents one decimal place movement. Dividing by 10 moves one place left, dividing by 100 moves two places left, and so on.
Add leading zeros! For example, if dividing 5 by 100, think of it as 5.0, then move two places left to get 0.05.
Multiplying by 100 moves the decimal point right two places, while dividing by 100 moves it left two places. They're opposite operations!
Yes, but moving the decimal is much faster and easier! Long division with powers of 10 takes more time and has more chance for arithmetic errors.
Remember: Division makes numbers smaller, so the decimal moves left. Multiplication makes numbers larger, so the decimal moves right.
