Multiply the whole equation by 4 to cancel out the fractions.
(2r = 5s/2 - s/4)*4
8r = 10s - s
8r = 9s
8r/9 = s
s = 8r/9

Answer:


s=(8r)/(9)

Explanation:

The given equation is


2r=(5s)/(2)-(s)/(4)

We need to solve this equation for s.

Simplify the right side of the equation.

Taking LCD on right side of the equation we get


2r=(2(5s)-s)/(4)


2r=(10s-s)/(4)


2r=(9s)/(4)

Multiply both sides by 4.


2r* 4=(9s)/(4)* 4


8r=9s

Divide both sides by 9.


(8r)/(9)=s

Interchange the sides.


s=(8r)/(9)

Therefore, the value of s is
s=(8r)/(9).
