如何简算:36.8%3.9%6.12

36.8-3.9-6.12 =36.8-(3.9+6.12) =36.8-(3.9+6.1+0.02) =36.8-10-0.02 =26.8-0.02 =26.78 谢谢,请采纳

3/8x12+5/8x36=3/8x12+5/8x(12+24)=3/8x12+5/8x12+5/8x24=(3/8+5/8)x12+5/8x24=12+15=27 3/8x12+5/8x36=3/8x12+(3/8+2/8)x36=3/8x12+3/8x36+2/8x36=3/8x(12+36)+1/4x36=18+9=27

36.8-3.9-6.88=36.8-6.8-3.9-0.08=30-3.9-0.1+0.02=26.2

36.9/(3.69 ×0.8) =(3.69×10)/(3.69 ×0.8) =10/0.8 =12.5

36.8-3.9-6.1 =36.8-(3.9+6.1) =36.8-10 =26.8

(1)4.36+8.3+3.64,=(4.36+3.64)+8.3,=8+8.3,=16.3;(2)37.7-(8.98+7.7),=37.7-7.7-8.98,=30-8.98,=21.02;(3)19.57-2.37-3.63,=19.57-(2.37+3.63),=19.57-6,=13.57;(4)8-7.24+5.87,=0.76+5.87,=6.63.

你好!!! 36×111+888×8 =36*111+111*8*8 =36*111+64*111 =(36+64)*111 =11100 希望能够帮助你!! 麻烦采纳,谢谢!

(1)23.75-8.64-3.36=23.75-(8.64+3.36)=23.75-12=11.75(2)17.83-9.5-7.83-0.5=17.83-7.83-9.5-0.5=(17.83-7.83)-(9.5+0.5)=10-10=0(3)3.45+8.7+16.55+1.3=(3.45+16.55)+(8.7+1.3)=20+10=30(4)8.54-5.96=8.54-(6-0.04)=8.54-...

21.36/2.9*0.8=77.43
