Find the order of each of the following elements in the respective groups:

Group	Element	Order
$\mathbb{Z}_{12} \times \mathbb{Z}_{16}$	$(7, 5 )$
$\mathbb{Z}_{12} \times \mathbb{Z}_{16}$	$(12, 7 )$
$\mathbb{Z}_{12} \times U(16)$	$( 7, 5 )$
$D_{12} \times U(16)$	$( a^{2}b^{1}, 5)$
$D_{12} \times Q_8$	$( a^{5}b^{1}, (-j) )$
