Correct answer: B
Key idea: multiply all numerators together and all denominators together to get the compound ratio.
Multiply the numerators: 5 × 7 × 6 = 210.
Multiply the denominators: 6 × 10 × 5 = 300.
Form the compound ratio and simplify: 210/300 = (divide both by 30) = 7/10 = 0.7.
Final answer: 0.7
