A2. In which conversion did Julia make a mistake?
(A) $24 \mathrm{dm}=2.4 \mathrm{~m}$
(B) $12^{\circ} 50^{\prime}=12.5^{\circ}$
(C) $0.4 \mathrm{~l}=4 \mathrm{~dl}$
(D) $3.6 \mathrm{~m}^{2}=36 \cdot 10^{3} \mathrm{~cm}^{2}$
(E) $130 \mathrm{~cm}=1.3 \cdot 10^{-3} \mathrm{~km}$
A2. Julija made a mistake in converting $12^{\circ} 50^{\prime}=12.5^{\circ}$, since $12.5^{\circ}=12^{\circ} 30^{\prime}$.
