Question

Which of these rational numbers is also an integer? 2/4 4/2 0.24 2.4

Answer 1

Number included in the rational number and also the integer:

$\boxed{\bold{\dfrac{4}{2}}}$

Further explanation

Numbers in mathematics can be divided into several terms

• 1. integer

numbers consist of positive, negative and 0 numbers

• 2. natural numbers

numbers consisting of positive numbers, starting with number 1

• 3. whole number

a number consists of positive numbers and zeros

• 4. prime number

numbers that can only be divided by numbers themselves and the number 1

And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.

Integers themselves consist of

• 1. positive integers the number to the right of the number 0 is 1,2,3 ...

• 2. negative integers the numbers to the left of the zeros are -1, -2, -3 ...

• 3. number 0

Integers themselves are numbers that are not expressed in the form of fractions

There are also rational numbers and irrational numbers

Rational numbers are numbers that can be expressed in simple fractions (by dividing two integers)

Can be stated in the form  :

$\large{\boxed{\bold{\frac{a}{b}}}$

where a and b = integer and

b ≠ 0

Let's check the choice of rational numbers from the questions above

• $\dfrac{2}{4}=\dfrac{1}{2}$

rational number but not an integer

• $\dfrac{4}{2}=2$

rational number and integer

• $0.24=\dfrac{24}{100}=\dfrac{12}{50}$

rational number but not an integer

•  $2.4=\dfrac{24}{10}=\dfrac{12}{5}$

rational number but not an integer

Answer 2

Answer:  The correct option is

(B) $\dfrac{4}{2}.$

Step-by-step explanation:  We are given to select the rational number that is also an integer :

$\dfrac{2}{4},~~\dfrac{4}{2},~~0.24,~~2.4.$

We have

$\dfrac{2}{4}=\dfrac{1}{2}=0.5,$ not an integer.

$\dfrac{4}{2}=\dfrac{2}{1}=2,$ an integer.

0.24 and 2.4 are not integers, they are just rational numbers.

Thus, the required rational number that is also an integer is $\dfrac{4}{2}.$

Option (B) is CORRECT.
