If `A:B=1/2:1/3, B:C=1/5:1/3` then `(A+B):(B+C)=`

If A:B=(1)/(2):(1)/(3),B:C=(1)/(5):(1)/(3) t, then (A+B):(B+C) is equal to :

If a:b=1 3/4: 2 2/3 and b:c=4: 3 1/4 then a:b:c=

The ratio of A:B=1:3,B:C=2:5,C:D=2:3 . Find the value of A:B:C:D

If a : b : c =1/4:1/3:1/2 , then a/b : b/c: c/a =? यदि a : b : c =1/4:1/3:1/2 , तो a/b : b/c: c/a =?

If a:b=3:1 and b:c=5:1 , then find the value of ((a^3)/(15b^2c))^3

If a:b=3:1 and b:c=5:1 , then find the value of a^2/(7bc)

If A=[[1 ,2,-3],[ 5, 0, 2],[ 1,-1, 1]], B=[[3,-1, 2],[ 4, 2 ,5],[ 2, 0, 3]] and C=[[4, 1, 2],[ 0, 3, 2],[ 1,-2, 3]] , then compute (A+B) and (B - C) . Also, verify that A + (B - C) = (A + B) - C .

If a=2b, then a:b=2:1 (b) 1:2( c) 3:4 (d) 4:3
