  1. x/3,15 = (0,15)/(7,2)
    => x.7,2 = 3,15 . 0,15
    => 7,2x = 0,4725
    => x = 0,4725 : 7,2
    => x = 0,065625
     

  2. $\frac{x}{3,15}=$ $\frac{0,15}{7,2}$
    →$\text{x:3,15=0,15:7,2}$
    →$\text{x:3,15=}$$\frac{1}{48}$ 
    →$\text{x=}$$\frac{1}{48}.3,15$ 
    →$\text{x=}$$\frac{21}{320}$
