Question

(-7 supra 11)+(-1 supra 4)+(+1 supra 2)+(-5 supra 22)​

Answer 1

Răspuns:

$= -\frac{27}{44}$

Explicație pas cu pas:

$-\frac{7}{11} - \frac{1}{4} + \frac{1}{2} - \frac{5}{22}$

Aducem toți termenii la același numitor (44):

$= \frac{-7*4 - 11 + 22 - 5*2}{44}$

$= \frac{-28 - 11 + 22 - 10}{44}$

$= -\frac{27}{44}$

Answer 2

Bună! ✨

$- \frac { 7 } { 11 } - \frac { 1 } { 4 } + \frac { 1 } { 2 } - \frac { 5 } { 22 } \\ \\ -\frac{28}{44}-\frac{11}{44}+\frac{1}{2}-\frac{5}{22} \\ \\ \frac{-28-11}{44}+\frac{1}{2}-\frac{5}{22} \\ \\ -\frac{39}{44}+\frac{1}{2}-\frac{5}{22} \\ \\ -\frac{39}{44}+\frac{22}{44}-\frac{5}{22} \\ \\ \frac{-39+22}{44}-\frac{5}{22} \\ \\ -\frac{17}{44}-\frac{5}{22} \\ \\ -\frac{17}{44}-\frac{10}{44} \\ \\ \frac{-17-10}{44} \\ \\ {}\boxed{ \frac{27}{44}}$

✔️ Succes! ✔️
