If `a:b=2:5` then `(3a+4b):(4a+5b)=`

If a:b=2:5, then (3a+2b)/(4a+b)=(16)/(13)( b) (13)/(16)(25)/(22)(d)(20)/(21)

If a:b=3:4 then find (3a+4b)/(4a-b)

If a : b = 2 : 3, then (3a+4b)/(4a+5b) is equal to : यदि a : b = 2 : 3, तो (3a+4b)/(4a+5b) बराबर है:

If a : b = 2: 5 , then ( 3a+ 4b) : (5a +6b) is equal to

If a:b=2:3 , then (5a+b):(3a+2b) is

If a:b=5:7 , then (5a-3b):(4a-2b) is equal to :

If a :b =3:5 find 2a +3b: 4a+5b

If (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5, then (3a + 5b) : (9a - 2b)=? यदि (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5 है, तो (3a + 5b) : (9a - 2b)=?

If a:b=2:5,. fid the value of (3a+2b)/(4a+b)
