Answer
$29.7^{\circ}$
Work Step by Step
To convert $29^{\circ} 40'$ to decimal degrees, let's break it as-
$29^{\circ} 40'$ = $29^{\circ}$ + $40'$
Now on dividing $40'$ by 60, we have the number of "decimal degrees" equivalent
to $40'$ (as $ 1^{\circ} = 60'$)
Therefore
$29^{\circ} 40'$ = $29^{\circ}$ + $(\frac{40}{60})^{\circ}$
$29^{\circ} 40'$ = $29^{\circ}$ + $0.666...^{\circ}$
$29^{\circ} 40'$ = $29^{\circ}$ + $0.7^{\circ}$ (Rounding to the nearest hundredth)
$29^{\circ} 40'$= $29.7^{\circ}$
