Question

How can you be sure that 0.56 ÷ 100 = 0.0056 ?

Answer 1

For every factor 10, move the decimal point one position. Pad with zeros where necessary. Dividing moves to the left, multiplication to the right.

So dividing by 100 is moving it 2 places to the left.

Answer 2

The correct answer is:  [A]: 
__________________________________________________
"When dividing by 100, move the decimal point two places to the left".
__________________________________________________
As such,  " 0.56 ÷ 100 = 0.0056" .

We take:  "0.56"  and move the decimal point two places to the left.  This means we point the decimal point to two "essentially imaginary zeros" places, or two "zeros" to the left, by increasing the number of zeros on the left, and then adding the decimal place.
