move the decimal down and over however many numbers are behind the decimal

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.

Move the decimal over to the left twice... 75. --- .75

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

To put a percent into decimal, simply move the decimal point over two places to the left, so 48.7 becomes .487

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%

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.

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.)

It is: 36/100 = 0.36 as a decimal

-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.

You move the decimal 2 places over.

Multiplying each number by 4 gives you the (decimated) .52 answer.

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

0.30 you move the decimal point over 2 times to the left to get the decimal. You move it over 2 times to the right to get the percent. IE. 5% = 0.05

0.364 ( move the decimal over two spaces to the left)

Move the decimal over two places, to get: 123.5%
