In this question,We are provided with Chapter "SIMPLE EQUATION".So,Let's Solve this Equation.
\begin{lgathered}\\\end{lgathered}
⇢3l=23×2⇢3l=43⇢l=43×3⇢l=49\begin{lgathered}\dashrightarrow{ \sf{3l = \dfrac{2}{3} \times 2}} \\ \\ \dashrightarrow{ \sf{3l = \dfrac{4}{3}}} \\ \\ \dashrightarrow{ \sf{l = \dfrac{4}{3 \times 3}}} \\ \\ \dashrightarrow{ \sf{l =} { \boxed {\sf {\green{\dfrac{4}{9}}}}}}\end{lgathered}
