Question

Which of the following statements is SOMETIMES true about rational numbers?

a) All rational numbers are integers.

b) The square √ of a rational number is always rational.

c) The sum of two rational numbers is always rational.

d) Rational numbers cannot be expressed as tions.

Answer 1

c) The sum of two rational numbers is always rational.

Step-by-step explanation:

The statement that is sometimes true about rational numbers is that the sum of two rational numbers is always rational. This means that when you add two rational numbers together, the result will always be another rational number.

For example, if you add 1/2 and 3/4, the sum is 5/4, which is a rational number.

However, it is important to note that not all rational numbers are integers (option a) or have rational square roots (option b).

Additionally, rational numbers can be expressed as fractions (option d). Therefore, the correct option is c) The sum of two rational numbers is always rational.
