8.25加3分之1乘以(2分之1加3分之1) =8.25+1/3X(1/2+1/3) =8.25+1/3X5/6 =8+1/4+5/18 =8+9/36+10/36 =8+19/36 =8又36分之19

126*(3/25) =126*0.12 =12.6+2.52 =15.12

1/[(1/4-1/10)x2/3] =1/[3/20x2/3] =1/[1/10] =10

6.23x10.1 =6.23x10+6.23x0.1 =62.3+0.623 =62.923 朋友,请及时采纳正确答案,下次还可能帮到您哦,您采纳正确答案,您也可以得到财富值,谢谢。

8/9-1/3÷7/18×2/3 =8/9-1/3×18/7×2/3 =8/9-4/7 =20/63 1/7-1/9×63-2/3 =1/7-7-2/3 =-7又11/21 8/15×3/4+7/16-1/4 =2/5+7/16-1/4 =32/80+35/80-20/80 =47/80

1/2×5/17+3/5÷1/3 =5/34+9/5 =25/170+306/170 =331/170

7分之2+(3分之1×7分之15)×35 =7分之2+7分之5×35 =7分之2+25 =25又7分之2 结果是25又7分之2

150×99 =150×(100-1) =150×100-150 =15000-150 =14850
