Răspuns :
( 5 / 2 ) × X = 125 / 18
18 × 5 X = 2 × 125
90 X = 250
X = 25 / 9
Verific: 5 / 2 x 25 / 9 = 125 / 18
[tex] \frac{5}{2} \times x = \frac{125}{18} \\ \\ \frac{5x}{2} = \frac{125}{18} \\ \\ 5x = \frac{125}{18} \times 2 = \frac{250}{18} \\ \\ 5x = \frac{125}{9} \\ \\ x = \frac{ \frac{125}{9} }{5} = \frac{125}{9 \times 5} = \frac{125}{45} = \frac{25}{9} [/tex]
