Fração:
- 11/18 - 2/3 =

Answer 1

$\large\sf{} - \dfrac{11}{18} - \dfrac{2}{3} \\\\ \large\sf{} -\left( \dfrac{11}{18} + \dfrac{2}{3} \right) \\ \\ \large\sf{} - \left( \dfrac{11}{18} + \dfrac{2 \times 6}{3 \times 6} \right) \\ \\ \large\sf{} - \left( \dfrac{11}{18} + \dfrac{12}{18} \right) \\\\ \large\sf{} - \dfrac{11 + 12}{18} \\ \\ \large\sf{}\bm{\large\boxed{\boxed{  { \large \sf - \dfrac{23}{18} }}}}$

${\large\boxed{\boxed{  { \large \sf Bons~Estudos }}}}$
