Problem
(1) How many times larger is \( \left(5.4 \times 10^{6}\right) \) than \( \left(9 \times 10^{3}\right) \) ? (A) \( 0.6 \times 10^{3} \) (B) \( 6 \times 10^{3} \) (C) \( 6 \times 10^{2} \) (D) \( 6 \times 10^{4} \)
Solution
Step 1 ：\( \frac{5.4 \times 10^{6}}{9 \times 10^{3}} \)
Step 2 ：\( \frac{5.4}{9} \times \frac{10^{6}}{10^{3}} \)
Step 3 ：\( 0.6 \times 10^{3} \)
