Question

como eu faço pra somar uma fração dentro de uma matriz? ​

Answer 1

Resposta:

Exatamente igual você soma elas fora da matriz, exemplo:

$\left[\begin{array}{cc}2&-4\\0&\frac{5}{2} \\\frac{4}{5} &2\end{array}\right] +\left[\begin{array}{cc}5&4\\6&\frac{7}{2} \\\frac{3}{5} &-4\end{array}\right]=\left[\begin{array}{cc}2+5&-4+4\\0+6&\frac{5}{2}+\frac{7}{2}\\\frac{4}{5}+ \frac{3}{5} &2-4\end{array}\right]$

$\left[\begin{array}{cc}2&-4\\0&\frac{5}{2} \\\frac{4}{5} &2\end{array}\right] +\left[\begin{array}{cc}5&4\\6&\frac{7}{2} \\\frac{3}{5} &-4\end{array}\right]=\left[\begin{array}{cc}7&0\\6&\frac{5+7}{2}\\\frac{4+3}{5} &-2\end{array}\right]$

$\left[\begin{array}{cc}2&-4\\0&\frac{5}{2} \\\frac{4}{5} &2\end{array}\right] +\left[\begin{array}{cc}5&4\\6&\frac{7}{2} \\\frac{3}{5} &-4\end{array}\right]=\left[\begin{array}{cc}7&0\\6&\frac{12}{2}\\\frac{7}{5} &-2\end{array}\right]$

$\left[\begin{array}{cc}2&-4\\0&\frac{5}{2} \\\frac{4}{5} &2\end{array}\right] +\left[\begin{array}{cc}5&4\\6&\frac{7}{2} \\\frac{3}{5} &-4\end{array}\right]=\left[\begin{array}{cc}7&0\\6&6\\\frac{7}{5} &-2\end{array}\right]$

Pronto! somamos duas matrizes com frações passo a passo.
