$\frac {2}{7}\times\frac{5}{9}\times\frac{3}{8}\times168 => \frac{2\times5\times3\times2\times2\times2\times3\times7}{7\times3\times3\times2\times2\times2}(Prime Factorisation)$ By cancelling we get $2\times5$ that is = 10.

$\frac { 2 }{ 7 } \quad \times \quad \frac { 5 }{ 9 } \quad \times \quad \frac { 3 }{ 8 } \quad \times \quad 168$ $\frac { 30 }{ 504 } \quad \times \quad 168\quad =\quad \frac { 5040 }{ 504 } \quad =\quad 10$

168 3/8 5/9*2/7 = 10

Three-eighths of168 = 63; five-ninths of 63 = 35; two-sevenths of 35 = 10
