Question

If y is inversely proportional to x and y =5 when x = 2 find the value of y when x = 8​

Answer 1

y = 10/8 = 1.125 or 1 1/4

Explanation:

Inverse proportion means

xy = a constant.

In this case, the constant is given by the example,

x = 2 when y=5, so

xy=10

when x = 8, then

y = 10/8 = 1.125 or 1 1/4
