Is zero a natural number?
No. Zero does not have a positive or negative value. However, zero is considered a whole number, which in turn makes it an integer, but not necessarily a natural number. Zero's status as a whole number and the fact that it is not a negative number makes it considered a natural number by some mathematicians.
Are negatives whole numbers ?
No
Are integers all negatives ?
No, they also include positive.
Are negatives rational?
The rational numbers includes all positive numbers, negative numbers and zero that can be written as a ratio (fraction) of one number over another. Whole numbers, integers, fractions, terminating decimals and repeating decimals are all rational numbers.
Can irrational numbers be whole numbers?
Irrational numbers can't be written as a ratio of two integers. The number is between integers, so it can't be an integer or a whole number.
Are negatives natural numbers?
NO. The natural numbers (or counting numbers) are the fundamental mathematical set on which all other arithmetic is based. They do not include negative numbers. (The set of integers provides negative numbers.)
Every whole number is a positive.
False, zero is a whole number and it is not positive.
Every integer is positive.
Integers are like whole numbers, but they also include negative numbers so false.
Every integer is a rational number.
True because to be an integer it has to be a whole number and whole numbers are rational like the number one .
Every real number is rational.
False, irrational numbers are real like for example (the number with the best name) Pi is real.l
Can natural numbers be irrational?
No. If a number is terminating or repeating, it must be rational; if it is both non terminating and non repeating, the number is irrational.The real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers.
Every whole number is an integer.
True
Integers are like whole numbers, but they also include negative numbers.
All integers are whole numbers.
Integers are like whole numbers, but they also include negative numbers so false
Are decimals rational numbers?
Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. So, any terminating decimal is a rational number.
If a number is real then it is irrational.
False, real numbers also consist of rational numbers.
Are all whole numbers natural?
No.
Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity so yes they are.
All whole numbers are real numbers.
True, the real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers. The set of real numbers is all the numbers that have a location on the number line.
Are real numbers whole numbers?
False, the real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers. The set of real numbers is all the numbers that have a location on the number line.
Is zero a rational number?
True, 0 can be written in the form a/b, where a = 0 and b is any non-zero integer. Hence, 0 is a rational number.
Irrational Numbers
A number that cannot be expressed as the ratio of two integers.
True or false: Every natural number is positive.
True because negatives are for taking away so it is not natural.
Whole number
Numbers that don't include any fractions or decimals. Examples: 0, 1, 2, 3, ...
Integers
Whole numbers including positive, negative and zero.
Every real number is rational or irrational.
True there is nothing in between, it is one or the other.
Provide an example of an irrational number.
Any number that cannot be represented as a ratio of integers because its decimal equivalent would go on forever
Pi is a classic example.
