$\frac{17}{48}$ of the water remains.
$\frac{7}{8} - \frac{3}{16} - \frac{1}{3}$ Find the LCM using prime factorization. 8 = 2 x 2 x 2 16 = 2 x 2 x 2 x 2 3 = 3 LCM = 2 x 2 x 2 x 2 x 3 = 48 Express as like fractions then subtract. $\frac{7}{8} - \frac{3}{16} - \frac{1}{3}$ = $\frac{42}{48} - \frac{9}{48} - \frac{16}{48}$ = $\frac{17}{48}$
