"Some integers are irrational numbers"

Answers

1. Answer :

"All integers are rational numbers"

True

Every integer is included in the set of rational numbers. Integers are a subset of the set of rational numbers.

2. Answer :

"No rational numbers are whole numbers"

False

A whole number can be written as a fraction with a denominator of 1, so every whole number is included in the set of rational numbers. The whole numbers are a subset of the rational numbers.

3. Answer :

"All rational numbers are integers"

False

Every integer is a rational number, but not every rational number is an integer. 

For example, rational numbers such as 3/5 and -5/2 are not integers. 

4. Answer :

"All integers are whole numbers"

False

Every whole number is an integer, but it is not true that every integer is a whole number.

Integers such as -1 and -6 are not whole numbers.

5. Answer :

"All whole numbers are rational numbers"

True

Whole numbers are a subset of the set of rational numbers and can be written as a ratio of the whole number to 1.

6. Answer :

"Some integers are irrational numbers"

False

All integers are rational numbers.
