Question

if P and Q very directly with each other then find the value of Q when P is equal to 7 and the constant of variation is 1 divided by 6

Answer 1

since P is directly proportional to Q

 P = K*Q where K is proportionality constant

given P =7 and K =1/6

put these value in above equation you will get

7 =1/6 * Q

Q = 7*6 = 42

I hope it is clear now.

Thanks
