The reason is because you have to make the number bigger when you multiply. When you move the decimal to the right you make the number bigger, when you move it to the left you make it smaller. Therefore, when you divide you must move the decimal to the left.

move the decimal point one place to the right - the answer is 151 :)
To write 0.08909 in standard form, you need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. In this case, you would move the decimal point four places to the right, resulting in 8.909 x 10^-2 in standard form.
Take, .000001 for example. We need to move the decimal 6 places to the right. This is the same as multiply by 10-6 .0.000001 =1x10-6
Product means numbers multiplied together. Multiplying by 10, 100, 1000 etc is easy, you just move the decimal point one place to the right for every zero. To find this product, move the decimal to the right 2 places in 3.8 and we have 380
Count the number of zeros to the left of the decimal point in the multiple of ten that you are using: Examples: 10 (1 zero); 1,000,000 (6 zeroes); 100.0 (2 zeroes) Move the decimal point to the right by that number of spaces (if you run out of spaces to move the decimal point then add a zero) Examples: 5 * 1,000 = 5000 .005 * 10000 = 50 5000 * 10 = 5000
