which of these afre integer

1/12 , -sqrt1 , TT, 1.75

5 answers

To determine which of the given options are integers, let's analyze each one:

  1. 1/12 - This is a rational number but not an integer, as it is a fraction.
  2. -sqrt1 - The square root of 1 is 1, so -sqrt1 = -1, which is an integer.
  3. TT - This appears to be a variable or symbol and does not correspond to an integer.
  4. 1.75 - This is a decimal number and is not an integer.

Thus, the only integer from the list is -1 (derived from -sqrt1).

what is 4/10

The fraction \( \frac{4}{10} \) can be simplified. Both the numerator (4) and the denominator (10) can be divided by 2:

\[ \frac{4 \div 2}{10 \div 2} = \frac{2}{5} \]

So, \( \frac{4}{10} \) simplifies to \( \frac{2}{5} \).

As a decimal, \( \frac{4}{10} = 0.4 \).

what is 4/10

whole number,rational number,real number,natural number,

Let's classify \( \frac{4}{10} \):

  1. Whole number: No, \( \frac{4}{10} \) is not a whole number, as whole numbers are non-negative integers (0, 1, 2, ...).

  2. Rational number: Yes, \( \frac{4}{10} \) is a rational number because it can be expressed as the quotient of two integers (4 and 10).

  3. Real number: Yes, \( \frac{4}{10} \) is a real number, as all rational numbers are a subset of real numbers.

  4. Natural number: No, \( \frac{4}{10} \) is not a natural number, since natural numbers are positive integers (1, 2, 3, ...).

In summary, \( \frac{4}{10} \) is a rational number and a real number, but it is neither a whole number nor a natural number.
