Answer
$18^{\circ}$ $48'$
Work Step by Step
To convert $18.8^{\circ}$ to degrees and minutes, let's break it as-
$18.8^{\circ}$ = $18^{\circ}$ + $0.8^{\circ}$
Now on multiplying 0.8 by 60, we have the number of minutes equivalent
to 0.8°
Therefore
$18.8^{\circ}$ = $18^{\circ}$ + $0.8(60')$
$18.8^{\circ}$ = $18^{\circ}$ + $48'$
$18.8^{\circ}$ = $18^{\circ}$ $48'$
