How to Multiply Decimals by 0.1, 0.01, 0.001 Mentally - Math Teacher Gon

Is 100 percent just 1?

If you want to convert a decimal value to a percentage, multiply by 100. The reason for this is that the value 1.0 and the fraction are both equal to 100%.

.00001. in math class = "one hundred-thousandths" in a machine shop = "Ten Millionths" Machine Shop examples: 12.3456 = Twelve inches, Three hundred forty-five thousandths and six tenths.

A millisecond (from milli- and second; symbol: ms) is a unit of time in the International System of Units (SI) equal to one thousandth (0.001 or 10^{−}^{3} or ^{1}/_{1000}) of a second and to 1000 microseconds.

1% of something means 1/100 of it. To calculate a percentage of a quantity, we use the same method as when we calculate a fractional part of that quantity because percent simply means a hundredth part. Therefore, percentages are just fractions.

Thus if expressed as a fraction with a numerator of 1, probability and odds differ by exactly 1 in the denominator: a probability of 1 in 100 (1/100 = 1%) is the same as odds of 1 to 99 (1/99 = 0.0101... = 0. 01), while odds of 1 to 100 (1/100 = 0.01) is the same as a probability of 1 in 101 (1/101 = 0.00990099... = 0.

A number that has a decimal point followed by digits that show the fractional part. Example decimal numbers: 0.01 (point zero one) which is also equal to 1/100.

One half has two different decimal expansions, the familiar 0.5 and the recurring 0.49999999... It has a similar pair of expansions in any even base. It is common to believe these expressions represent distinct numbers: see the proof that 0.999...

Multiply 0.5 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number. 50/100 is 50 over 100 and means 50 per 100. 50 "per 100" means 50 "percent" or 50%.
