Question

if b by a is equal to 0.25 then to a minus b by 2 a + b + 2 by 3 is equal to what​

Answer 1

hey mate

here is the answer...

Answer:

given:

b/a=0.25

=>b/a=1/4

=>a/b=4/1 [invertendo]

[multiplying both sides by 2]

=>2a/b=8/1

applying componendo and dividendo property of the ratios,

=>(2a+b)/(2a-b)=(8+1)/(8-1)

=>(2a+b)/(2a-b)=9/7

=>(2a-b)/(2a+b)=7/9 [Invertendo]

thus,

(2a-b)/(2a+b)+2/3=7/9+2/3

=>(2a-b)/(2a+b)+2/3= (7+6)/9

=>(2a-b)/(2a+b)+2/3= 13/9
