The quotient of a number t and 4.2 is at most 15.

frosja888 [35]

Answer:

$t \leq 63$

Step-by-step explanation:

Quotient of two numbers also means the result of the two numbers after division.

If the quotient of a number t and 4.2 is at most 15., this can be expressed using the inequality;

$\dfrac{t}{4.2}\leq 15$ (note that at most 15 means that the highest value we can have is 15 after taking the quotient of the number hence the reason of the inequality sign.)
