3/8+1/6 = \\\\=\frac{3}{8}+1/6\\\\=\frac{3}{8}+\frac{1}{6}\\\\=\frac{13}{24}

9/10-1/4=\\\\=\frac{9}{10}-1/4\\\\=\frac{9}{10}-\frac{1}{4}\\\\=\frac{13}{20}

5/9+2/6=\\\\=\frac{5}{9}+2/6\\\\=\frac{5}{9}+\frac{2}{6}\\\\=\frac{8}{9}

11/15-1/2=\\\\=\frac{11}{15}-1/2\\\\=\frac{11}{15}-\frac{1}{2}\\\\=\frac{7}{30}
