Question

Write an inequality to represent the following:
The width of the picture is shorter than 8.5.

  1. w < 8.5    
  2. w = 8.5    
  3. w > 8.5    
  4. w ≤ 8.5    

Hint:

We are given a statement. We have to write the expression of inequality for the given statement. We have to see the limits given for the required value.

The correct answer is: w < 8.5


    The given statement is as follows:
    The width of the picture is shorter that 8.5.
    Let the width of the picture be represented using the variable “w”.
    The width of the picture is shorter than 8.5 means, the width cannot be greater than the given value. It cannot be equal to the given value too.
    So, the width is less  tha 8.5
    The sign for less than 8.5 is “< 8.5”
    The mathematical representation of the inequality is as follows:
    w < 8.5
    This is the given inequality.

    For such questions, we have to be careful about the limits of the given quantity.
