What is the easiest way to divide a decimal by 10, 100, or 1000?
To divide by powers of 10, move the decimal point to the left by as many zeros as there are in the divisor. For example, dividing by 100 moves the decimal point two places to the left.
Can a fraction always be converted into a decimal?
Yes, any fraction can be converted into a decimal by dividing the numerator by the denominator, or by scaling the denominator to a power of 10.
