[tex] 3\frac{1}{2}= \frac{3\cdot2+1}{2}= \frac{7}{2} \\ \\ 2\frac{3}{4}= \frac{2\cdot4+3}{4}= \frac{11}{4} \\ \\ [/tex]
7/2.........................x+21600
11/4.........................x
[tex]x\cdot \frac{7}{2} = \frac{11}{4}\cdot(x+21600) \\ \\ x\cdot2\cdot7=11(x+21600) \\ \\ 14x=11x+21600 \\ \\ 14x-11x=21600 \\ \\ 3x=21600 \\ \\ x=7200 [/tex]
a doua muncitoare a incasat 7200 lei, iar prima cu 21600 mai mult, deci a incasat 93600 lei
