2/11+9/11乘以(3.2+2又34/35) 4/5除以5+5除以4/5乘以4/15 （1.8+2/9乘以3又3/4）+2又19/30 全都简便计算
1.
(2/11+9/11)*(3.2+2+34/35)
=5+48/35
=6又13/35
2.
4.5/(5+5)/(4/5)*4/15
=4.5*(5/4)*(1/10)*4/15
=1*2/75
=2/75
3.
(1.8+2/9*3又3/4)+2又19/30
=(9/5+2/9*15/4)+79/30
=25/30+54/30+79/30
=79/30*2
=79/15
(2/11+9/11)*(3.2+2+34/35)
=5+48/35
=6又13/35
2.
4.5/(5+5)/(4/5)*4/15
=4.5*(5/4)*(1/10)*4/15
=1*2/75
=2/75
3.
(1.8+2/9*3又3/4)+2又19/30
=(9/5+2/9*15/4)+79/30
=25/30+54/30+79/30
=79/30*2
=79/15
2/11+9/11乘以(3.2+2又34/35) 4/5除以5+5除以4/5乘以4/15 （1.8+2/9乘以3又3/4
1除以(1乘以2乘以3)加上1除以(2乘以4乘以3)加上1除以(3乘以4乘以5)加上.1除以(8乘以9乘以10)
=3乘以2乘以1,=4乘以3乘以2乘以1,=5乘以4乘以3乘以2乘以1,那么100!除以99!
1除以1乘以2+1除以2乘以3+1除以3乘以4+1除以4乘以5````1除以42乘以43的值
（2又1/2003乘以9又5/8+2002/2003乘以9.625）除以96又1/4
2.6乘以18分之11+2又5分之3除以2又7分之4+26乘以0.4简便运算
计算题:(1)4又2分之1乘以[-3^2乘以(-3分之一)^+0.8]除以(-5分之3)
3又5分之一除以5/4乘以87.5%
奥数题11.1乘以4除以9乘以3除以7.4乘以2
{5又9分之5减去0.8+2又9分之4}乘以{7.6除以5分之4+2又5分之4乘以1.25},等于?
{5又9分之5减去0.8+2又9分之4}乘以{7.6除以5分之4+2又5分之2乘以1.25},等于多少?
用递等式计算,7/9乘以3/14乘以3/4,12除以6/7除以2/3,2/5乘以2/3除以1/6,3/10除以5/6乘以
