* 100 = $\frac{3.142-(3+\frac{1}{8})}{3+\frac{1}{8}}\cdot 100$ =

$\frac{3.142-(3+\frac{1}{8})}{3+\frac{1}{8}}\cdot 100$ =

$\frac{3.142-3-\frac{1}{8}}{3+\frac{1}{8}}\cdot 100$ =

$\frac{0.142-0.125}{3+\frac{1}{8}}\cdot 100$ =

$\frac{0.017}{3+\frac{1}{8}}\cdot 100$ =

$\frac{0.017}{\frac{25}{8}}\cdot 100$ =

$\frac{0.017\cdot 8}{25}\cdot 100$ =

$\frac{0.136}{25}\cdot 100$ =

$\frac{0.136\cdot 4}{1}$ =
