写写过程啊,谢了,我就选你为最佳
追答
一.125*3+125*5+25*3+25 = (3+1)*125+(3+1)*25 =1100 二. 7/8 + ( 1/8 + 1/9 )= 7/8+1/8+1/9 =10/9 三.(23/4-3/4)*(3*6+2) = 5*20 =100 四. 3/7 × 49/9 - 4/3 = 3/7*49/9-4/3 =17/3 五. 8/9 × 15/36 + 1/27 =11/27 六. 12× 5/6 – 2/9 ×3 =28/3 七. 8× 5/4 + 1/4 =41/4 八. 6÷ 3/8 – 3/8 ÷6 =255/16 九. 4/7 × 5/9 + 3/7 × 5/9 = (4/7+3/7)*5/9 =5/9 十. 5/2 -( 3/2 + 4/5 )= 5/2-3/2-4/5 =1/5 没写过程的直接四则运算就行了 不难的四则运算 都可以约分母或分子   修改的回答不能分行  看起来乱了点~~
