1. The problem is to understand the expression "it is not d/a b/c or q/b?" and clarify its meaning. 2. This looks like a question about fractions or ratios, possibly comparing or combining them. 3. Let's interpret the expressions: "d/a", "b/c", and "q/b" are fractions. 4. The phrase "not d/a b/c or q/b" is ambiguous, but it might mean "not equal to d/a, b/c, or q/b" or "not in the form of these fractions." 5. Without additional context, it's unclear what operation or comparison is intended. 6. Please provide a clearer or more complete question for precise help.
