Answer 2

$5/18+11/18-13/18\\\\=\frac{5}{18}+\frac{11}{18}-\frac{13}{18}\\\\\frac{5}{18}+\frac{11}{18}\\\\=\frac{5+11}{18}\\\\=\frac{16}{18}\\\\=\frac{8}{9}\\\\=\frac{8}{9}-\frac{13}{18}\\\\\frac{8}{9}-\frac{13}{18}\\\\=\frac{16}{18}-\frac{13}{18}\\\\=\frac{16-13}{18}\\\\16-13=3\\\\=\frac{3}{18}\\\\\mathrm{Eliminar\:o\:fator\:comum:}\:3\\\\=\frac{1}{6}$
