$1\dfrac{1}{16}$
Convert the mixed number to improper fraction: $=\dfrac{8(1)+3}{8}-\left(+\dfrac{5}{16}\right) \\=\dfrac{11}{8}-\dfrac{5}{16}$ Make the fractions similar using their LCD, which is $16$: $\\=\dfrac{11(2)}{8(2)}-\left(\dfrac{5}{16}\right) \\=\dfrac{22}{16}-\left(\dfrac{5}{16}\right) \\=\dfrac{22-5}{16} \\=\dfrac{17}{16} \\=1\dfrac{1}{16}$
