p supra 100*120=36 . va rog frumos.

Răspuns :

[tex]\frac{P}{100}*120=36 \\ \frac{P}{100}=\frac{36}{120} \\ \frac{P}{100}=0,3 \\ P=0,3*100 \\ P=30[/tex]
[tex]\displaystyle \frac{P}{100} \cdot 120=36 \Rightarrow \frac{120P}{100} =36 \Rightarrow 120P=100 \cdot 36 \Rightarrow 120P=3600 \Leftrightarrow \\ \\ \Leftrightarrow P= \frac{3600}{120} \Rightarrow P= 30[/tex]
