\(=\dfrac{5}{8}+\dfrac{7}{10}=\dfrac{50}{80}+\dfrac{56}{80}=\dfrac{106}{80}=\dfrac{53}{40}\)
\(\dfrac{5}{8}+\dfrac{7}{10}=\dfrac{25+28}{40}=\dfrac{53}{40}\)
\(\dfrac{5}{8}+\dfrac{7}{10}=\dfrac{50}{80}+\dfrac{56}{80}=\dfrac{53}{40}\)
\(\dfrac{5}{8}\) + \(\dfrac{7}{10}\) = \(\dfrac{50}{80}\) + \(\dfrac{56}{80}\) = \(\dfrac{53}{40}\)
