Answer :
Multiply each side by p, so
kp = ar
Divide each side by a, so
kp/a = r
The answer is the third option
kp = ar
Divide each side by a, so
kp/a = r
The answer is the third option
K=ar/p
multiply both sides by p to eliminate the fraction
Kp=ar
divide both sides by a
kp/a=R
R=kp/a
hope this helps
