The quotient of a number and 4.2 is less than 21.
The quotient of 4.2 and a number is less than or equal to 21.
The quotient of 4.2 and a number is less than 21.

Answer 1

"The quotient of a number and 4.2 is less than or equal to 21."

Reason: "The quotient of a number and 4.2" means n ÷ 4.2 (n/4.2), and "less than or equal to" matches ≤. The others either use "<" (not ≤) or invert the quotient (4.2 divided by the number).
