$18^{\circ}$ $48'$
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 $18.8^{\circ}$ = $18^{\circ}$ + $0.8(60')$ $18.8^{\circ}$ = $18^{\circ}$ + $48'$ $18.8^{\circ}$ = $18^{\circ}$ $48'$
