Question

Which of these inequalities means that 18 is greater than three times a number?

Answer 1

hello!

Let's write this verbal phrase as an inequality.

First of all, let the number be n.

"three times n" can be written like so:-

$\pmb{3n}$

Now, 18 is greater than 3n:-

$\pmb{18 > 3n}$

Which means 3n is less than 18:-

$\bigstar{\boxed{\pmb{3n < 18}}}$

note:-
