Multiplying 0.02468 by a positive power of 10 will shiȇ the decimal point to the right. Simply shiȇ the decimal point to the right until the result is greater than 10,000. Keep track of how many times you shiȇ the decimal point. Shiȇing the decimal point five times results in 2,468. This is still less than 10,000. Shiȇing one more place yields 24,680, which is greater than 10,000.
Answer: 6
