Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
One to one
When you multiply by ten to a power, move the decimal point to the right by the number of places of the power. 3.6 x 10 ^4 move decimal 4 places to right = 36000
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
rounded to two decimal places after the decimal point: 6.73
Three decimal places.A simple rule of thumb for multiplying decimals; ignore the decimals and just multiply the number together.0.111 x 0.1; would become 111 x 1 = 111Then count all the numbers after the decimal. 0.111 (3) and 0.1 (1) 3+1=4And put the decimal point that many places from the right.With four places 111 becomes:11.1 ( one place)1.11 (two places)0.111 (three places)0.0111 (four places)0.111 x 0.1 = 0.0111----------------------------There is 2 decimals digits in hundredths and 1 decimal digit in tenths, thus when multiplied together they will have 2 + 1 = 3 decimal digits.However, if the decimal digits on the right hand end are zero they are not written, and less than 3 can be written.Examples:0.97 × 0.3 = 0.2910.17 × 0.3 = 0.0510.12 × 0.5 = 0.060 = 0.06When multiplying decimal numbers, multiply them without the decimal point and then put the decimal point back in to the result by counting the total number of digits after the decimal points in the original numbers and ensuring that the same number are in the result.Thus as the first number has 2 decimal places and the second that 1 decimal place, the result will have 1 + 2 = 3 decimal places.
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.

1, to the right
It moves three places to the right.
Exactly what you have when you just move the decimal point three places to the right from where it originally is.
105 To multiply a number by 100, just move the decimal point two places to the right. (To divide a number by 100, just move the decimal point two places to the left.)
One to one
Move the decimal point two places to the right and add a % sign.
Ignore the decimal point, multiply, count the places to the right of the decimal point, then count the same number from left to right in the answer,( after you add if nessicary) And put the decimal there. There's your answer. Example: 5 x 0.2 = 1.0 unusually, the number gets smaller after you add the decimal point.
Move the decimal point three places to the right.
2510 To multiply a number by 100 move the decimal point two places to the right.
