3.7×0.32+0.37×3.6+0.037×22
=0.037×(100×0.32)+0.037×(10×3.6)+0.037×22
=0.037×32+0.037×36+0.037×22
=0.037×(32+36+22)
=0.037×90
=0.037×(100-10)
=0.037×100-0.037×10
=3.7-0.37
=3.33
=0.037×(100×0.32)+0.037×(10×3.6)+0.037×22
=0.037×32+0.037×36+0.037×22
=0.037×(32+36+22)
=0.037×90
=0.037×(100-10)
=0.037×100-0.037×10
=3.7-0.37
=3.33
