  1.  51/35 \times 105/13 \times 39/17
    = \frac{51 \times 105 \times 39}{35 \times 13 \times 17}
    = \frac{3 \times 3 \times 3 }{1\times1\times1}
    = 27
     

  2. $\frac{51}{35}$ x $\frac{105}{13}$ x $\frac{39}{17}$ 
    = $\frac{51. 105.39}{35.13.17}$ 
    = $\frac{3.3.3}{1.1.1}$ 
    = 27
