Problem
A lab has two bacteria cultures. Culture \( A \) contains \( 8 \times 10^{4} \) bacteria, and culture \( B \) contains \( 4 \times 10^{6} \) bacteria. How do the two cultures compare in size? A Culture \( A \) contains twice as many bacteria as culture \( B \). B Culture \( A \) contains \( \frac{1}{2} \) as many bacteria as culture \( B \). C Culture \( A \) contains \( \frac{1}{25} \) as many bacteria as culture \( B \). D Culture \( A \) contains \( \frac{1}{50} \) as many bacteria as culture \( B \).
Solution
Step 1 ：\(\text{Calculate the ratio }\frac{\text{Culture A}}{\text{Culture B}}\)
Step 2 ：\(\frac{8 \times 10^{4}}{4 \times 10^{6}}\)
Step 3 ：\(\frac{1}{50}\)
