Answer

$16^{\circ}$ $15'$

Work Step by Step

To convert $16.25^{\circ}$ to degrees and minutes, let's break it as- $16.25^{\circ}$ = $16^{\circ}$ + $0.25^{\circ}$ Now on multiplying 0.25 by 60, we have the number of minutes equivalent to 0.25° Therefore $16.25^{\circ}$ = $16^{\circ}$ + $0.25(60')$ $16.25^{\circ}$ = $16^{\circ}$ + $15'$ $16.25^{\circ}$ = $16^{\circ}$ $15'$
