Studdy Solution

STEP 1

Assumptions1. The natural numbers are the set of all positive integers, starting from1. . Negative numbers, fractions, decimals, and irrational numbers are not considered natural numbers.

STEP 2

We need to identify the natural numbers from the list provided. Let's start with option A.
Option A is -7. Negative numbers are not considered natural numbers, so option A is not a natural number.

STEP 3

Next, let's consider option B.
Option B is 38\frac{3}{8}. Fractions are not considered natural numbers, so option B is not a natural number.

STEP 4

Now, let's consider option C.
Option C is 0.250 . \overline{25}. This is a decimal number, and decimal numbers are not considered natural numbers, so option C is not a natural number.

STEP 5

Finally, let's consider option D.
Option D is 9\sqrt{9}. The square root of9 is3, which is a positive integer. Therefore, option D is a natural number.

STEP 6

Now, let's consider option.
Option states that there are no natural numbers in this list. However, we have identified that option D is a natural number. Therefore, option is incorrect.
The natural numbers in the list are D. 9\sqrt{9}.
