7分之5*11分之6*7/10 3/4*(9/10%5/6) (1/5+1/9...

你好: 7分之5*11分之6*7/10 =5/7×6/11×7/10 =3/11 3/4*(9/10-5/6) =3/4×1/15 =1/20 (1/5+1/9)*45 =1/5×45+1/9×45 =9+5 =14 23/25*1/4+1/4*2/25 =1/4×(23/25+2/25) =1/4×1 =1/4 101*3/10-3/10 =3/10×(101-1) =3/10×100 =30

(9分之8+1又7分之3+10分之6)除以(11分之3+7分之5+9分之4) =(8/9+10/7+6/10)除以(3/11+5/7+4/9) =(560/630+900/630+378/630)除以(189/693+495/693+308/693) =(1838/630)除以(993/693) =(1838/630)X(693/993) =(919/105)X(...

裂项法: 1-1/2+5/6-7/12+9/20-11/30 =1-1/2+1/2+1/3-1/3-1/4+1/4+1/5-1/5-1/6 =1-1/6 =5/6

这个题主要就是要注意:圆括号,加号、减号、乘号与取余的优先级与结合性。 其中,圆括号优先级最高,乘号和取余第二,加号和减号最低 结合性均是从左到右。 10 + 9 * ((8 + 7) % 6) + 5 * 4 % 3 * 2 + 3 =10 + 9 * (15% 6) + 5 * 4 % 3 * 2 + 3...
