Moving a decimal point to the right is the same as multiplying a number by a power of ten. As long as both numbers are multiplied by the same amount, they will retain their same relationship.
No.
When dividing decimals, if there is a decimal in the divisor, you should move the decimal point in the divisor to the right until it becomes a whole number. You must then move the decimal point in the dividend the same number of places to the right. Once both numbers are adjusted, you can proceed with the division as usual.
To divide decimals, first, eliminate the decimal point from the divisor by multiplying both the divisor and the dividend by the same power of 10. Then, perform the division as you would with whole numbers. Finally, place the decimal point in the quotient directly above where it would appear in the dividend, based on the number of decimal places in the dividend. Adjust the quotient if necessary to ensure accuracy.
The result of dividing 700,000,000 by 37 is approximately 18,918,919. The division can be done by dividing the whole number part of the dividend (700,000,000) by the divisor (37) and then adding any remaining decimal places of the dividend divided by the divisor.
The decimal point moves 3 places to the right.
No.
No.
It is moved 9 places.

The decimal point moves 3 places to the right.
When dividing decimals, you move the decimal point to the right in the divisor (the number you are dividing by) to make it a whole number. You must then move the decimal point in the dividend (the number being divided) the same number of places to the right. This ensures that the division remains equivalent. The result will have its decimal point placed according to the new position of the decimal in the dividend.
You can move the decimal point in both the divisor and the dividend when dividing because this process maintains the overall ratio of the numbers. By shifting the decimal point to the right in both numbers by the same number of places, you effectively multiply both by the same power of ten, which does not change the value of the quotient. This simplification makes the division easier while keeping the result accurate.
When working with decimals, the primary rules include aligning the decimal points when adding or subtracting, which ensures accurate placement of values. For multiplication, the total number of decimal places in the product should equal the sum of the decimal places in the factors. In division, the divisor should be made a whole number by moving the decimal point, and the same number of places should be moved in the dividend. Lastly, rounding rules apply when necessary, typically rounding to a specified number of decimal places.
To divide by a decimal, make the divisor a whole number by moving the decimal point to the right; the dividend must also be changed by moving its decimal point the same number of digits to the right. So to divide 0.5 by 0.57, make the divisor 0.57 into 57 by moving the decimal point two digits to the right, then also move the decimal point of the dividend (0.5) two places to the right to give 50. Thus: 0.5 / 0.57 = 50 / 57 ~= 0.88
If the dividend is between 2.25*10k and 10k+1 where k is any integer, then the decimal point does not move while if the dividend is between 10k and 2.25*10k then the decimal point moves 1 place to the left.
