Introduction and properties of inequations
Check if the following inequalities are true or false:
$103 > 25 $
$-62 > 4.5 $
$42 \leqslant \dfrac{84}{2} $
$-4 > -5 $
$1 > 1 $
$0 < 3 < -3.1 $
- $103$ is greater than $25$.
- $-62$ is a negative number, so it is less than $4.5$ (nombre positiu).
- $84$ divided by $2$ is $42$, hence the expression is correct: $42$ is equal to $42$.
- $-4$ is greater than $-5$ (since the numbers are negative).
- $1$ is equal to $1$, but $1$ is not greater than $1$, in any case, it would be correct if we said that $1$ is greater than or equal to $1$.
- In this case, we have a double inequality. We have to check that both inequalities are true: $0$ is less than $3$, but $3$ is not less than $-3.1$ since this is a negative number. Consequently, the expression is false.
