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 :)

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

When we multiply by 109 this means we are multiplying by 10 nine times. This has the effect of moving the decimal point 9 places to the right.So, if we move the decimal 2 places we get 156 and then if we move it 7 places more this is the same as adding 7 zeroes to the end of the number.Thus the answer is 1,560,000,000 (1 billion & 560 million)
