\dfrac{5}{16}+\dfrac{3}{20}+\dfrac{7}{20}+\dfrac{5}{16} = \dfrac{25}{80}+\dfrac{12}{80}+\dfrac{28}{80}+\dfrac{25}{80} = \dfrac{25+12+28+25}{80} = \dfrac{90}{80} = 1\dfrac{10}{80} = 1\dfrac{1}{8}
\dfrac{5}{16}+\dfrac{3}{20}+\dfrac{7}{20}+\dfrac{5}{16} = \dfrac{25}{80}+\dfrac{12}{80}+\dfrac{28}{80}+\dfrac{25}{80} = \dfrac{25+12+28+25}{80} = \dfrac{90}{80} = 1\dfrac{10}{80} = 1\dfrac{1}{8}
