MaxineUse the following rules:
1. Any negative number on a temperature scale is colder than any positive number on the same scale.
2. If both numbers are positive, the one with the lower absolute value is colder than the one with the higher absolute value.
3. If both numbers are negative, the number with the higher absolute value is colder than the one with lower absolute value.
In this instance, rule 3 applies; therefore, -2C is less cold than -24C.

How do you know whether to shade in the circle when putting inequalities on a number line?
If it is 'less than' or 'greater than' or 'not equal' then use an open circle.If it is 'less than or equal to' or 'greater than or equal' then use the shaded circle.
Is 43 mg bigger than 5g?
No 43 mg equals 0.043 g which is obviously less than 5 g.
How do you know when to use the less than symbol and when to use the less than or equal to symbol when writing an inequality for a situation?
It depends upon whether the inequality is strictly less than (<), or if it is less than or could be equal (≤). For example: if x < 6, x can have any value less than 6, but cannot have the value 6; but if x ≤ 6, x can have any value less than 6, but can also have the value 6. Or put another way, x = 6 is NOT a solution of x < 6, but IS a solution to x ≤ 6.
