Chapter SH, Problem 2.1.8EP

To determine

The correct inequality for the given expression

Answer to Problem 2.1.8EP

  $-15<12$

Explanation of Solution

Given information:

  $-15\circ 12$

Concept Used:

When two quantities are not equal, the comparison between them is often presented by certain symbols, this comparison is known as inequality and the symbols used for such comparison are known as inequality symbols.

There are four inequality symbols, $>$ , $<$ , $\ge$ , $\le$ namely “greater than”, “less than”, “greater than or equal to” and “less than or equal to” respectively.

Calculation:

In the given expression-

  $-15\circ 12$

We can clearly say that $-15$ is smaller than $12$ and it would lie to the left on the number line, hence the inequality will be given by-

  $-15<12$
