Explicație pas cu pas:

a)

$\dfrac{^{2)}2}{5} + \dfrac{3}{10} = \dfrac{4}{10} + \dfrac{3}{10} = \dfrac{4+3}{10} = \dfrac{7}{10}$

b)

$\dfrac{2}{9} + \dfrac{^{3)}2}{3} = \dfrac{2}{9} + \dfrac{6}{9} = \dfrac{2+6}{9} = \dfrac{8}{9}$

c)

$\dfrac{^{2)}3}{4} + \dfrac{5}{8} = \dfrac{6}{8} + \dfrac{5}{8} = \dfrac{6+5}{8} = \dfrac{11}{8} = 1\dfrac{3}{8}$

d)

$\dfrac{7}{8} + \dfrac{^{4)}1}{2} = \dfrac{7}{8} + \dfrac{4}{8} = \dfrac{7+4}{8} = \dfrac{11}{8} =1\dfrac{3}{8}$

e)

$\dfrac{^{2)}1}{2} + \dfrac{1}{4} = \dfrac{2}{4} +\dfrac{1}{4} = \dfrac{2+1}{4} = \dfrac{3}{4}$

f)

$\dfrac{3}{10} + \dfrac{^{2)}2}{5} = \dfrac{3}{10} + \dfrac{4}{10} = \dfrac{3+4}{10} = \dfrac{7}{10}$

g)

$\dfrac{1}{6} + \dfrac{^{2)}2}{3} = \dfrac{1}{6} + \dfrac{4}{6} = \dfrac{1+4}{6} = \dfrac{5}{6}$

g)

$\dfrac{^{4)}3}{5} + \dfrac{1}{20} = \dfrac{12}{20} + \dfrac{1}{20} = \dfrac{12+1}{20} = \dfrac{13}{20}$
