2. Which is the smallest?

(a) -1,

(b) -1/2,

(c) 0,

(d) 3.

The smallest number among the given options is (a) -1.

To determine the smallest number among the given options, you need to compare their values. Let's compare the values one by one:

(a) -1: This is a negative number, which means it is smaller than positive numbers.

(b) -1/2: This is a negative fraction. To compare it with other numbers, we need to convert it to a decimal. Dividing -1 by 2 gives us -0.5, which is a smaller value than -1.

(c) 0: Zero is neither positive nor negative. It is smaller than positive numbers but greater than negative numbers.

(d) 3: This is a positive number, which is greater than any negative number or zero.

So, among the options given, the smallest number is (b) -1/2 because -0.5 is the smallest decimal value among the given options.

To determine the smallest value, we need to compare the given options:

(a) -1,
(b) -1/2,
(c) 0,
(d) 3.

Let's compare them one by one:

-1 is smaller than -1/2 because it is a more negative value. So, -1 is smaller than -1/2.

-1/2 is smaller than 0 because 0 is neither positive nor negative. So, -1/2 is smaller than 0.

-1/2 is smaller than 3 because 3 is a positive value. So, -1/2 is smaller than 3.

Therefore, the smallest value among the given options is -1.
