# Carlos drank 2,740 mL of water after football practice. How many Liters did he drink?

$2.740 \cdot L$
$1 \cdot m L$ $=$ $1 \times {10}^{-} 3 L$, i.e. $\text{m}$ denotes multiplication by ${10}^{-} 3$.
So, $2 , 740 \cdot \cancel{m L} \times {10}^{-} 3 \cdot L \cdot \cancel{m {L}^{-} 1} = 2.740 \cdot L .$
