Question

if y is directely proportional to 1/x and x = 2 when y = 20 what is the value of x when y = 1.252

Answer 1

y directly proportional to 1/x.
so x* y = constant.
x1* y1 = x2* you
2 *20 = x * 1.252
x = 40/1.252

Answer 2

Hey there !!!!

~~~~~~~~~~~~~~~~~~~~~~~~~~

y is directly proportional to 1/x

⇒⇒⇒ y=k/x  k=constant

y*x=constant

y₁x₁=y₂x₂

y₁=20   x₁=2   y₂=1.252   x₂=??

20*2= 1.252*x₂

40/1.252 =x₂

x₂=31.94
