1又5分之4X[2又3分之1+(4.6-2又5分之1)除以2.4]

这道题先根据文字叙述列出正确的算式 3又1/2+4又3/5-2又1/2-4.6 =1+4.6-4.6 =1

5.2×(3/8+4.625)=5.2×5=26

4.6×8加4又5分之3×2 =4.6×8+4.6×2 =4.6×(8+2) =4.6×10 =46

=6又1/3-4.6-2/5-2.3+2/3 =(6又1/3+2/3)-(4.6+2/5)-2.3 =7-5-2.3 =2-2.3 =-0.3

4.6×8+四又五分之三×2 =4.6×(8+2) =4.6×10 =46

4.6x(3又2/5+6又3/5)÷2.3 =4.6x10÷2.3 =46÷2.3 =20

=3.2*(1+0.2)+4.6 =3.2+0.64+4.6 =8.44

(4.6-3.2)×11.5 =1.4*11.5 =(1+0.4)*11.5 =1*11.5+0.4*11.5 =11.5+4.6=16.1

(4.6+3.4÷2)x0.5 =4.6x0.5+3.4÷2x0.5 =2.3+1.7x0.5 =2.3+0.85 =3.15 谢谢,请采纳
