Answer
$18^{\circ}$ $45'$
Work Step by Step
To convert $18.75^{\circ}$ to degrees and minutes, let's break it as-
$18.75^{\circ}$ = $18^{\circ}$ + $0.75^{\circ}$
Now on multiplying 0.75 by 60, we have the number of minutes equivalent
to 0.75°
Therefore
$18.75^{\circ}$ = $18^{\circ}$ + $0.75(60')$
$18.75^{\circ}$ = $18^{\circ}$ + $45'$
$18.75^{\circ}$ = $18^{\circ}$ $45'$
