Question

Why are you allowed to move the decimal points before dividing with decimals? Explain your reasoning.

Answer 1

Answer:

If you move the decimal point the same number of places in the dividend and the divisor, you are multiplying them both by the same power of 10. That does not change the quotient.

Answer 2

"The same number of places in the dividend and the divisor, you are multiplying them both by the same power of 10" allowed to move the decimal points before dividing with decimals.

Step-by-step explanation:

• When you divide a decimal number by 10, move the decimal point to the left by one place. When you divide a decimal number by 100, move the decimal point to the left by two places.
• When you're working with whole numbers, you can multiply or divide any number by 10 just by moving the decimal point to the right or left, respectively. When you multiply by moving the decimal point to the right, you also need to add a zero to the end of it.
• Place the decimal point in the answer by starting at the right and moving a number of places equal to the sum of the decimal places in both numbers divided.
