3/2a=3/5b=2/3c,求a:b:c
3/2a=3/5b=2/3c,求a:b:c
3/2a=3/5b=2/3c,求a:b:c
3/2a=3/5b=2/3c,
全部化成a再比较.b=3/2÷3/5a=5/2a
c=3/2÷2/3a=9/4a
a:b:c=a:5/2a:9/4a=4:10:9 【同时乘以4】
希望我的回答能帮助到您,
已知:(a-b)(b-c)(c-a)/(a+b)(b+c)(c+a)=5/132,求a/(a+b)+b/(b+c)+c/(c+a)的值!(请尽快,我有急用,a/(a+b)+b/(b+c)+c/(c+a)=1/2[(a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a)]+3/2 (a-b)/(a+b)+(b-c)/(b+c)+(c-a)/(c+a) 没有错吧...
已知A=3A-4B+C,B=5A+4B+2C,求[1]A-B;[2]A+B;[3]2A-3B.
1/a=2/b=3/c求a+b-c/a-b+c=?
15a:12b:9c=3a:2b:c,求a:b:c求出a:b:c
已知|a|=2,|b|=3,|c|=5,且|a+b|=a+b,|a+c|= -(a+c),求a-b-c的值
a:b=5:3,b:c=2:3求a:b:c
如果a;b=2:3,b:c=6:5,求a:b:c.
已知a:b=5:6,b:c=2:3 求a:b:c
已知a:b=3:4和b:c=5:2求a:b:c
如果|4a-5b|+(3b-c)^2=0,求a:b:c
3a=2b,b:c=4:3,求a:b:c 3a=2b,b:c=4:3,求a:b:c
2a-b+3c=0,3a+b-c=0求a:b:
已知a:b=3:4,a:c=2:5,求a:b:c
已知a-b=3,a-c=4,求4a-(b-c)*(b-c)-2b-2c
已知a/(b+2c)=b/(c+2a)=c/(a+2b),且a+b+c≠0,求(3b+c)/b的值?
a^2(b+c)+b^2(a+c)+c^2(a+b)+3abc=0,a^2+b^2+c^2=1求a+b+c
已知b+c分之a=a+c分之b=a+b分之c,求a+b-3c分之2a+2b+c
观察:a+(2b-3c)=a+2b-3ca-(2b-3c)=a-2b+3c求a-b+c=a-( ) (a-b+c-d)(a+b-c+d)=[a-( )][a+( )]
