D. A rational number can be written as a fraction p/q
Step-by-step explanation:
All real numbers are classified into two major categories namely rational and irrational numbers.
A number which can be written in the form
, p and q are integers and q ≠ 0 is called a rational number.
Ex:
5 is a rational number since 5 can be written as
and clearly, 1 ≠ 0
0 is also rational since 0 can be written as
.
A number which cannot be written in the form
is called an irrational number.
Ex:
Hence, the correct option is D.

The remainder when 4z is divided by 8 is 4
From the question, when z is divide by 8, the remainder is 5. But we do not know the quotient.
From the formula
Here, the dividend is z, divisor is 8, and the remainder is 5.
Let the quotient be x, then we can write that
Now, to determine the remainder when 4z is divided by 8,
Multiply both sides of the equation by 4
Then,
Compare this to the formula![\frac{Dividend}{Divisor}= Quotient + \frac{Remainder}{Divisor}](/tpl/images/0246/7308/e8e65.png)
The remainder is 4
Hence, the remainder when 4z is divided by 8 is 4.
