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

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

If a/b=2/3 then find the values of (4a+3b)/(3b)

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

If (2a+b)/(a +4b)=3 , then find the value of (a+b)/(a+2b)

If (2a+ b)/(a+4b) = 3 , then find the value of (a+b)/(a+2b)

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

Choose the correct alternative answer for each of the following question. If a:b =5:3 , then what is the value of (3a +2b) :(3a-2b) ?
