Practice problem
The original matrix was [352935824]\begin{bmatrix}3&5&2\\9&3&5\\8&2&4\end{bmatrix}398532254 and the new matrix is [0003515131236]\begin{bmatrix}0&0&0\\\frac35&\frac15&\frac13\\12&3&6\end{bmatrix}0531205130316. What row operations were performed?
23 R3⟶R3\frac23\ R_3\longrightarrow R_332 R3⟶R3
32 R3⟶R3\frac32\ R_3\longrightarrow R_323 R3⟶R3
0R1⟶R10R_1\longrightarrow R_10R1⟶R1
18 R1⟶R1\frac18\ R_1\longrightarrow R_181 R1⟶R1
3R2⟶R23R_2\longrightarrow R_23R2⟶R2
15 R2⟶R2\frac15\ R_2\longrightarrow R_251 R2⟶R2
115 R2⟶R2\frac1{15}\ R_2\longrightarrow R_2151 R2⟶R2
Type a concept, like “slope” or “photosynthesis”.
