What are methods that can be used to determine where to put the decimal point when multiplying?
move the decimal down and over however many numbers are behind the decimal
What is 1000 x 0.285?
1000 x 0.285= 285Explanation/Shortcut!!!! :)The number 1000 contains three zeros, 0s. Whenever you are MULTIPLYING a number by 10,100,1000, 10000, etc... move the decimal to the LEFT, making the number bigger. If you move the decimal point in 0.285 over three times (from the three zeros), it comes up with 285.NOTE: The decimal moves to the RIGHT when you are DIVIDING.
What are the methods to move over decimals in multiplication?
You don't need to move the decimal, just put the decimal as many spaces over in your answer as there are in the two numbers multiplyed. Example: 1.2 x 1.22 = 1.464
What is 0.12 x 1000?
.12x1000 = 120This questions is the kind of thing you can punch into a calculator and solve so I'm going to assume you want a complete explanation.When multiplying decimals by any multiple of ten (ie. 100, 10000, 10000000000000) simply count the number of zero's and move the decimal place to the right that many times.There are three zero's in the number 1000 so you should move the decimal place over three times to the right in the number .121st move: 1.22nd move: 12.03rd move: 120 (This is your solution)
What is 48.7 percent as a decimal?
To put a percent into decimal, simply move the decimal point over two places to the left, so 48.7 becomes .487
