1. **State the problem:** Solve the equation $$\frac{2tq}{5} = 0$$ for the variable $tq$. 2. **Recall the rule:** A fraction equals zero if and only if its numerator is zero (and the denominator is not zero). 3. **Apply the rule:** Since the denominator 5 is not zero, set the numerator equal to zero: $$2tq = 0$$ 4. **Solve for $tq$:** $$tq = \frac{0}{2}$$ $$tq = 0$$ 5. **Final answer:** $$tq = 0$$ This means the product $tq$ must be zero for the fraction to be zero.
