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
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
When do you move the decimal places to the right?
Well, honey, you move the decimal to the right when you're multiplying by powers of 10. It's as simple as that. Just count how many zeros are in the power of 10 and shift that decimal over to the right that many places. Easy peasy lemon squeezy!
What is 0.625 converted to percent?
To convert decimal to percent, just move the decimal place over two to the right (which is basically multiplying by 100). Therefore, 0.625 = 62.5%
48 is what percent of 144?
33%To find this out, you do 48/144=.33333. Move the decimal over to the right twice (multiplying by 100) and you get your percentage.
Why Do you move decimal points over when multiplying?
If you just pull some numbers out of the air and practice with them, you'll discover that whenever you multiply or divide a number by ten (10), you wind up with exactly the same digits as you started with, and the only difference is that the decimal point is moved over one place. Knowing this trick, you should always keep it in your tool box. If you have to do an arithmetic problem and it has a multiplication or division by 10 in it, you don't have to go through the whole procedure. All you have to do is move the decimal point over one place. (Of course, you also have to know which way to move it.)
What is 14 times 25?
-14 x 2.5 = -3514x2.5_____70+ 280_____350 Since we are multiplying by decimals we need to look at the 2.5. The decimal moves over one space, so in our answer we need to move the decimal over one place. This makes the answer 35.0. Also since we were multiplying by a (-) we need to multiply 35.0 by (-) and get -35.0.
What is 36 over 100 in decimal points?
It is: 36/100 = 0.36 as a decimal
When writing a percent as a decimal why do you move the decimal point 2 places?
You move the decimal point over two places because a percent means per 100 so therefore you move the decimal point over to the hundredth place
How do make a decimal a percent?
You move the decimal 2 places over.
What is 13 over 25 in a decimal?
Multiplying each number by 4 gives you the (decimated) .52 answer.
How do you multiply two decimal numbers together?
Pretend there are no decimal points, and multiply the numbers together. Then count over (from the right) the number of decimal points of the two numbers combined. For example: 3.4 * 0.185 = 0.6290 34 * 185 = 6290. There is one number to the right of the decimal point in 3.4, and three to the right in 0.185. One plus three is four, so starting from 6290. you move over four places.
How do you make percentarges?
to make percentages like 40% of 70 you'd change the percentage 40% to a decimal so 40% becomes .40 and you multiply (remember multiplying decimals multiply normally and when you're done move the decimal over by how many numbers are behind the decimal)answer : 2870*.40-----28.00
