(1)原式=(5.6+5.4-0.9)*0.375=3.75+0.0375=3.7875
(2)=(3.25+6.75)*36=360
(3)=18又2/3-1又1/3-(4.59+6.41)=17+1/3-10=7又1/3
(1)原式=5.6×3/8+3/8×5.4-3/8×0.9
=(5.6+5.4-9/10)×0.375
=10.1×0.375
=(10+0.1)×0.375
=3.75+0.0375=3.7875
(2)原式=3.25×36+6.75×36=(3.25+6.75)×36...
全部展开
(1)原式=5.6×3/8+3/8×5.4-3/8×0.9
=(5.6+5.4-9/10)×0.375
=10.1×0.375
=(10+0.1)×0.375
=3.75+0.0375=3.7875
(2)原式=3.25×36+6.75×36=(3.25+6.75)×36=10×36=360
(3)原式=18又2/3-1又1/3(-4.59+6.4)=17又1/3-10=7又1/3
(4)原式=10又1/6-(11/4× 8/11+2/3×5/4)=10又1/6-(2+5/6)=10又1/6-2又5/6=7又1/3

(1)3/8=0.375,0.375×(5.6+5.4-0.9)
(2)(100×325×0.36+100×6.75×36 )÷100
=(325×36+675×36 )÷100
=36×(325+675)÷100
=360
