  1. Giải đáp+Lời giải và giải thích chi tiết:
     2 + $\dfrac{3}{5}$ = $\dfrac{10}{5}$ + $\dfrac{3}{5}$ = $\dfrac{3}{5}$
    $\dfrac{5}{6}$ : 2 = $\dfrac{5}{6}$ x $\dfrac{1}{2}$ = $\dfrac{5}{12}$
    1 – $\dfrac{12}{5}$ = $\dfrac{5}{5}$ – $\dfrac{12}{5}$ = $\dfrac{-7}{5}$
    3 x $\dfrac{1}{2}$ = $\dfrac{3}{2}$

  2. 2+3/5
    =10/5+3/5
    =13/5
    5/6:2
    =5/6:2/1
    =5/6 xx 1/2
    =(5xx1)/(6xx2)
    =5/12
    1-12/5
    =5/5-12/5
    =(5-12)/5
    3xx1/2
    =3/1xx1/2
    =(3xx1)/(1xx2)
    =3/2.
