Work Step by Step
25$\frac{1}{2}$ days to 2$\frac{5}{6}$ hours
$\frac{25\times2 +1}{2}$ to $\frac{2\times6 +5}{6}$
= $\frac{50 +1}{2}$ to $\frac{12 +5}{6}$
= $\frac{51}{2}$ to $\frac{17}{6}$
= $\frac{51}{2}$ $\div$ $\frac{17}{6}$
= $\frac{51}{2}$ $\times$ $\frac{6}{17}$
= $\frac{51\times6}{2\times17}$
= $\frac{17\times3\times3\times2}{2\times17}$
=$\frac{3\times3}{1}$
=$\frac{9}{1}$
=9
