The range of numbers within 1.5 of is from to .

Solution

To determine the range of numbers that are within of , we set up the inequality
This inequality means that can be at most away from .
  1. Write the inequality without absolute value:
  1. Next, add to each part of the inequality to solve for :
  1. Convert to fraction form for ease of computation: .
  2. Express and with a common denominator. The common denominator for and is :
  1. Now compute the lower bound:
  1. Compute the upper bound:
Thus, the range of numbers is from to .
Comparing with the provided options, the correct one is:
J. to .

The Deep Dive

To find the range of numbers within 1.5 of the number , we start by converting into a decimal, which is approximately 0.67. Adding and subtracting 1.5 from this gives us the range:

Thus, the range extends from to , so G is the correct choice.
Choosing an option that gives us a better visual of this range in the number line is also useful! You can think of it as a span that captures all the values from the left extreme, , to the right extreme, , encasing the cozy spot around . It helps in understanding how far out you can go while staying “close” to that middle number!
