125%=1.25 ；5/4=1.25
所以3.7乘以125%+1.25乘以2.7+5/4乘以3.6的简便运算为：
（3.7+2.7+3.6）乘以1.25=12.5
原式化简：
3.7*1.25+1.25*2.7+1.25*3.6
=1.25*(3.7+2.7+3.6)
=1.25*10
=12.5
3.7×125％+1.25×2.7+5/4×3.6=3.7*1.25+1.25*2.7+1.25*3.6=(3.7+1.25+3.6)*1.25=10*1.25=12.5
3.7×125％+1.25×2.7+5/4×3.6
解：原式=1.25(3.7+2.7+3.6)
=1.25×10
=12.5
3.7×125％+1.25×2.7+5/4×3.6
=3.7×1.25+1.25×2.7+1.25×3.6
=(3.7+2.7+3.6)×1.25
=10×1.25
=12.5
