132*1946-946

 

Answer 1

\(\frac{1946\times1316+1000}{\left(1+131\right)\times1946-946}\)

\(\frac{1946\times131+1000}{1946\times131+1000}\)

\(=1\)

Answer 2

\(\frac{1946\times131+1000}{132\times1946-946}\)

\(=\frac{1946\times131+1000}{\left(131+1\right)\times1946-946}\)

\(=\frac{1946\times131+1000}{1946\times131+1946-946}\)

\(=\frac{1946\times131+1000}{1946\times131+1000}\)

\(=1\)
