Question

Which of the statements is true

Answer 1

Answer:

The only valid choice is c.

Step-by-step explanation:

Rational Numbers

Rational numbers have the form a/b, where a and b are integers and b is not zero.

In other words, rationals are all numbers that can be written as a fraction.

Examples are -3/7, 11/2, 5, 0

Note the last two numbers are integers, but they are also rationals because an integer can be expressed as a fraction with a denominator of 1.

Irrational numbers are the opposite, they cannot be expressed as a fraction.

a. $\sqrt{7}$ is not an integer since it's irrational. False

c. $\sqrt{25}$ = 5 or -5. It is a rational number because it's an integer. True

b. $\sqrt{16}$ = 4 or -4. It is not an irrational number because it's an integer. False

d. 190 is a rational number. False

The only valid choice is c.
