32 x 27 + 148 x 34 + 16 x 94
= ( 32 x 27 + 16 x 94 ) + 74 * 2 * 34
= 32 ( 27 + 47 ) + 74 x 68
= 32 x 74 + 74 x 68
= ( 32 + 68 ) x 74
= 100 * 74
= 7400
\(\frac{2017\cdot2013-2017}{4034\cdot1006+2007}\)
\(=\frac{2017\cdot\left(2013-1\right)}{2017\cdot\left(2012+1\right)}\)
\(=\frac{2012}{2013}\)

a, 32×27+148×34+16×94
=32×27+74×2×34+16×2×47
=32×27+74×68+32×47
=32×(27+47)+74×68
=32×74+74×68
=74×(32+68)
=72×100
=7200
b, 2017×2013-2017 / 4034×1006+2017
=2017×(2013-1) / 2017×2×1006+2017
=2017×2012 / 2017×2012+2017
=1/2017
