-11.5 -9.5<br><br> How do they compare select the symbol.<br><br> &lt; = &gt;
inn [45]

Answer:

The symbol is <, because -11.5 < -9.5

Step-by-step explanation:

The number line is arranged from smallest to greatest numbers, and when you read the numbers you start from left to right, so the numbers in the left are smaller than the number in the right

In the set of the negative numbers, the greatest value is the smallest number

Examples

-1 is greater than -2  because -2 lies before -1 on the number line

∵ The numbers are -11.5 and -9.5

∵ The number -11.5 is before the number -9.5 on the number line

- That means -11.5 is smaller than -9.5

∴ -11.5 < - 9.5

∴ The symbol is <
