$34^{\circ}$ $27'$

Work Step by Step

To convert $34.45^{\circ}$ to degrees and minutes, let's break it as- $34.45^{\circ}$ = $34^{\circ}$ + $0.45^{\circ}$ Now on multiplying 0.45 by 60, we have the number of minutes equivalent to 0.45° Therefore $34.45^{\circ}$ = $34^{\circ}$ + $0.45(60')$ $34.45^{\circ}$ = $34^{\circ}$ + $27'$ $34.45^{\circ}$ = $34^{\circ}$ $27'$
