Question

When a power of 10 moves from the numerator to the denominator, the sign of the exponent changes true or false

Answer 1

Answer:

True

Explanation:

If the power of 10 moves from numerator to denominator or reverse their sign changes to opposite. Considering 1/1000, we can write this as power of 10 as -3 in the numerator. Also the decimal is shifted in the numerator to the left when power of ten is dividing and to the right when its in multiplication up to the places equal to the number of zero  like 1/100 = 0.01 and 1.03*100=103
