Answer:

Every Rational number when multiply by 0.5 produces a rational number.

Step-by-step explanation:

Rational Number is a number that can be changed in the formation of \frac{p}{q}, where p & q are real numbers and q ≠ 0.

Even a natural number can also be a rational number since it can be change into \frac{number}{1}

So, the every rational number when multiply by 0.5 produces a rational number. For example: 2 × 0.5 = 1 (rational number)

7 × 0.5 = 3.5 (rational number)

42.63 × 0.5 = 21.315 (rational number)

But, \sqrt{2}\times0.5 = irrational as it has non terminating decimal number (also \sqrt{2} is irrational number)

Fiesta28 [93]
X = number of servers
y = number of guests

\text {number of guest per table = } 4<span>

</span>\text {number of tables = } \dfrac{y}{4}
<span>
</span>\text {number of servers needed = } \dfrac{y}{4} \div 12<span>

</span>\text {number of servers needed = } \dfrac{y}{4} \times  \dfrac{1}{12}

\text {number of servers needed = } \dfrac{y}{48}

There must be at least 1 server for every 12 tables:
x \geq \dfrac{y}{48}
