  1. đây nhé no copy nha
    = 1946,131 + 1000/1946,131 + 1946 – 946
    = 1946,131 + 1000/1946,131 + 1000
    = 1

  2. $\dfrac{1946.131+1000}{132.1946-946}$
    $=\dfrac{1946.(132-1)+1000}{132.1946-946}$
    $=\dfrac{132.1946-1946+1000}{132.1946-946}$
    $=\dfrac{132.1946-(1946-1000)}{132.1946-946}$
    $=\dfrac{132.1946-946}{132.1946-946}$
    $=1$
