Question

1.5×7.4+0.6×150%+2÷3分之2 37分之33×36 5又7分之6-（8分之3-7分之1）

37分之33×38 1.5×7.4+0.6×150%+2÷3分之2 （简便计算）

Answer 1

简便计算

1.5×7.4+0.6×150%+2÷(2 /3)
解，得：
==1.5×7.4+0.6×1.5+2*(3/2)
==1.5×7.4+0.6×1.5+2*1.5
==1.5×(7.4+0.6+2)
==1.5×10
==15

(33/37)×36
解，得 ：
==(33/37)×(37-1)
==(33/37)×37-(33/37)×1
==33-(33/37)
==32又33/37

5又7分之6-（8分之3-7分之1）
解，得：
==(41/7)-[(3/8)-(1/7)]
==(41/7)+(1/7)-(3/8)
==6-(3/8)
==5又5/8

37分之33×38
解，得：
==(33/37)*38
==(33/37)*(37+1)
==(33/37)*37+(33/37)*1
==33+(33/37)
==33又33/37

1.5×7.4+0.6×150%+2÷3分之2
解，得：
1.5×7.4+0.6×150%+2÷(2 /3)
==1.5×7.4+0.6×1.5+2*(3/2)
==1.5×7.4+0.6×1.5+2*1.5
==1.5×(7.4+0.6+2)
==1.5×10
==15
