The heights h of two-thirds of the members of a population satisfy the inequality |h-68.5/2.7|≤1 where h is measured in inches.Determine the interval on the real number line in which these heights lie.

assuming parentheses to make it

|(h-68.5)/2.7|≤1

(otherwise there'd be no reason to have a numeric fraction, as written)

|h-68.5| <= 2.7

so, h is within 2.7 of 68.5, and

65.8 <= h <= 71.2
I solved it already but thanks for the great help! It just confirmed my answer.:)
Why didn't use the two third value
Why didn't use the two third value of h in this problem
In this problem what is the meaning of two thirds of members
