Pablo has to paint $\frac{1}{3}$ more murals.
Painted mural to jar of paint ratio: $\frac{2}{3} paintedmurals: \frac{4}{5} jarofpaint$
Simplify the ratio.
$\frac{1}{3} paintedmurals: \frac{2}{5} jarsofpaintused$
Pablo needs 2/5 jars of paint per each 1/3 painted murals
$3*\frac{2}{5}$
$\frac{6}{5}$
