1:()=5/8=25÷()=()%怎么做?
8*x=6/25/1/5
(25+5)/(1-3/8-3/8)+25=145
1=5 2=25 3=125 4=625 5=?6=?7=?8=?...
25/( )=5/8=1:( )=( )%=( ) (填小数)
25÷( )=8分之5=1:( )=( )%=( )(填小数)
2*8=25%=3:( )=5/( )=( )/24
数学几分之几?例:1 5 --- = --- = 0.5 2 10 12 ----= ---- = 25 1 ---= --- = 8
口算:1/2-1/3= 4/5-8/25= 13/20+7/100=
口算.9/16×8= 8/25×5/8=
解方程 (1+25%)x=5/8
5分之1×8÷X=25分之6
8×x=25/6÷5/1 怎么解
x-1又8分之5=25分之7
1·25+3/4-12/5-8/3=?
7分之8乘( )=( )乘25=5分之3乘( )=1
5分之1*()=25分之3*()=9分之2*( )=( )*5分之8=1
5/12X+1/4=8/21 1/5*÷X=6/25
