(i) The statement is false. (ii) The true statement would be: If $I=prt$, then $t=\dfrac{I}{pr}$.

Work Step by Step

Solve for $t$ by dividing by $pr$ on both sides of the given equation: $\dfrac{I}{pr} = \dfrac{prt}{pr} \\\dfrac{I}{pr} = t \\t = \dfrac{I}{pr}$ Thus, the given statement is false. The true statement is: If $I=prt$, then $t=\dfrac{I}{pr}$.
