Answer 1

Ejercicio 1)

$\frac{5}{8}+\frac{3}{4}+x=\frac{9}{4}\\\\\frac{11}{8}+x=\frac{9}{4}\\\\\frac{11}{8}+x-\frac{11}{8} =\frac{9}{4} -\frac{11}{8}\\\\x=\frac{7}{8}$

Ejercicio 2)

$\frac{1}{6}+\frac{2}{3}+x=2\\\\\frac{5}{6}+x=2\\\\\frac{5}{6}+x-\frac{5}{6}=2-\frac{5}{6}\\\\x=\frac{7}{6}$

Ejercicio 3)

$\frac{10}{5}+\frac{5}{10}+x=4\\\\\frac{5}{2}+x=4\\\\\frac{5}{2}+x-\frac{5}{2}=4-\frac{5}{2}\\\\x=\frac{3}{2}$
