(36-4a)/8=136-4a=84a=36-84a=28a=7
3200÷4÷25=3200÷(4×25)=3200÷100=32
(a2-2a-3)/(a2-3a-4)=0(a-3)(a+1)/(a-4)(a+1)=0(a-3)/(a-4)=0a-3=0a=3a+1/a=3+1/3=10/3
11.8÷0.25÷4=11.8÷(0.25×4)=11.8×1=11.8
-7除以3-14除以3=-(7+14)÷3=-21÷3=-7(-3.5)/7/8*(-3/4)=3.5*8/7*3/4=4*3/4=3【(+1又3/4)-(-7/8)+(-7/12)】除以(-7/8)
=1÷(2-2/3×6/5)=1÷(2-4/5)=1÷6/5=5/6
1÷(1+5/8÷5)=1÷(1+5/8×1/5)=1÷(1+1/8)=1÷9/8=1×8/9=8/9这已经是最简便的方法了
0.325乘0.8加0.55除以5/4减3/5除以8/7=0.325×0.8+0.55×4/5-3/5×7/8=(0.325+0.55)×0.8-3/5×7/8=7/8×0.8-3/5×7/8=7/8
90000÷125÷2÷8=90000÷(125×8)÷2=90000÷1000÷2=90÷2=45祝开心
=1*3/2*4/3*5/4*6/5*7/6*8/7约掉之后=4
40X8÷2/5=40X8X5/2=40X20=800再问:呃。
36-4a=84a=36-8=28a=7
4.75=19/41.36=34/250.375=3/8(19/4)*(34/25)*(3/8)/(19/4)/(34/25)/(3/8)=(19/4)/(19/4)*(34/25)/(34/25)*
这样写:(36-4a)/8=0
2-1/2=1+1/2=3/2,同理,2-2除以3=4/3.(2-2002除以2003)=2004/2003推出它们的乘积为2004/2=1002
这可不是方程(32-4a)÷8=4-0.5a
(a-5)/(a+1)>0a-5>0a+1>0或a-5-1或a
先求分母的最小公倍数,为(a-1)*6,即左式上下同乘6,右式上下同乘(a-1)
共有5种算法:1/(2/3)/4/(5/6/7/8)/9=2.81/(2/(3/4))/(5/6/7/8)/9=2.81/(2/(3/4/5)/6/7/(8/9))=2.81/(2/(3/4/(5/6
