Rate this question:

• 2.

### The whole numbers are 0, 1, 2, 3,

• A.

True

• B.

False

A. True
Explanation
The statement is true because the whole numbers include 0 and all positive integers. The numbers 0, 1, 2, and 3 are all whole numbers as they are non-negative integers. Therefore, the given statement is correct.

Rate this question:

• 3.

### Which of the following are integers?

• A.

4

• B.

-3.2

• C.

-5

• D.

0

A. 4
C. -5
D. 0
Explanation
-3.2 is not an integer because it has a decimal part to it.
7/2 is not an integer because it is equation 3.5 which has a decimal part.

Rate this question:

• 4.

### 0 is what type of number(s)?

• A.

Integer

• B.

Whole

• C.

Natural

A. Integer
B. Whole
Explanation
0 is considered an integer because it is a whole number that can be expressed without a fractional or decimal component. It is also considered a whole number because it is not a fraction or a decimal. Therefore, the correct answer is Integer, Whole.

Rate this question:

• 5.

### Decimals, whole numbers, and natural numbers can ALL be rational numbers....if we CAN put them into a FRACTION!

• A.

True

• B.

False

A. True
Explanation
Decimals, whole numbers, and natural numbers can all be expressed as fractions. A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. Since decimals, whole numbers, and natural numbers can all be written in fraction form, they can all be considered rational numbers. Therefore, the statement is true.

Rate this question:

### 62.454545...(to infinity) is a rational number because it has a _________________ decimal.

repeating, Repeating, REPEATING
Explanation
62.454545...(to infinity) is a rational number because it has a repeating decimal. In this case, the decimal part of the number, which is 454545...(to infinity), repeats indefinitely. A rational number can be expressed as a ratio of two integers, and since the repeating decimal can be written as a fraction (in this case, 62.45/99), it is considered a rational number.

Rate this question:

• 7.

### 1.815 is a rational number because it has a _____________ decimal.

terminating, Terminating, TERMINATING
Explanation
The number 1.815 has a terminating decimal because the digits after the decimal point eventually end, and there are no repeating patterns. This means that the number can be expressed as a fraction in the form of p/q, where p and q are integers and q is not equal to zero.

Rate this question:

• 8.

### What is the MOST SPECIFIC name for the numbers listed below: ...-2,-1,0,1,2...

integers, integer, integer number, Integer, INTEGER, INTEGERS
Explanation
The most specific name for the given numbers is "integers." Integers are whole numbers that can be positive, negative, or zero, and they include the numbers -2, -1, 0, 1, and 2. The terms "integer," "integer number," "Integer," "INTEGER," and "INTEGERS" all refer to the same concept of these whole numbers.

Rate this question:

• 9.

### Is zero a negative or a positive number?

• A.

Negative

• B.

Positive

• C.

Neither negative or positive....just 0!

C. Neither negative or positive....just 0!

### How do you say this number?  -6

• A.

Minus 6

• B.

Negative 6

• C.

Negative minus 6

B. Negative 6
Explanation
The correct answer is "negative 6" because the negative sign (-) in front of the number indicates that it is less than zero. In this case, the number is specifically -6, which means it is six units to the left of zero on the number line.

Rate this question:

• 11.

### Natural numbers greater than 0 are positive?

• A.

True

• B.

False

A. True
Explanation
Natural numbers are a set of numbers that start from 1 and go infinitely in a positive direction. Since they start from 1, which is a positive number, all natural numbers greater than 0 are positive. Therefore, the statement "Natural numbers greater than 0 are positive" is true.

Rate this question:

• 12.

### Which integer has a lower value?

• A.

-300

• B.

-500

• C.

Both have the same value

B. -500
Explanation
Hint: Which is further away from 0?

Rate this question:

• 13.

### -4 is what type of number?

• A.

Integer

• B.

Whole

• C.

Natural

A. Integer
Explanation
The number -4 is an integer because it is a whole number that can be positive, negative, or zero. It is not a natural number because natural numbers are positive integers starting from 1. Similarly, it is not a whole number because whole numbers include all positive integers and zero, but not negative numbers. Therefore, the correct classification for -4 is an integer.

Rate this question:

• 14.

### Which of the following are whole numbers?

• A.

-4

• B.

0

• C.

4

• D.

8.6

B. 0
C. 4
Explanation
Whole numbers are a set of numbers that include all the positive integers (including zero) and their negatives. In this case, the numbers 0 and 4 are whole numbers because they are both positive integers and their negatives (-4) are also included in the set. However, 8.6 is not a whole number because it is a decimal and not an integer.

Rate this question:

• 15.

### Which of the following are Real Numbers?

• A.

Natural Numbers

• B.

Repeating Decimals

• C.

Integers

• D.

Whole Numbers

A. Natural Numbers
B. Repeating Decimals
C. Integers
D. Whole Numbers
Explanation
Natural numbers, integers, and whole numbers are all subsets of real numbers. Natural numbers are positive counting numbers, including zero. Integers are whole numbers and their negatives. Whole numbers are non-negative integers. Repeating decimals can also be represented as real numbers, as they can be expressed as a fraction or decimal. Therefore, all the options listed are real numbers.

Rate this question:

• 16.

### All Rational Numbers can be put into a _________________.

• A.

Whole number

• B.

Fraction

• C.

Decimal

B. Fraction
Explanation
All Rational Numbers can be put into a fraction because a rational number can be expressed as the ratio of two integers. In other words, it can be written in the form of a fraction, where the numerator and denominator are both integers. This allows us to represent rational numbers accurately and precisely.
