Four is no less than the quotient of a number x and 2.1

The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).

Explanation:
"No less than" means it can be more than this or equal to, so we use 4 greater than or equal to.
Quotient means division, so we write x/2.1.

To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.
