See a solution process below:

Explanation:

We can write this equation:

$t hours = 20 chairs$ $t" hours" = 20" chairs"$

We can now multiply each side of the equation by $3$ $color(red)(3)$ to find the number of chairs Mr. Lee can paint in 3 hours if he paints them continuously at the same rate.

$3 \times t hours = 3 \times 20 chairs$ $color(red)(3) xx t" hours" = color(red)(3) xx 20" chairs"$

$3 t hours = 60 chairs$ $3t" hours" = 60" chairs"$

Mr. Lee can paint 60 chairs in $3 t$ $3t$ hours.
