## Is 26 a composite number

Yes, since 26 has more than two factors i.e. 1, 2, 13, 26. In other words, **26 is a composite number** because 26 has more than 2 factors.

## Is 26 a rational number

**26 is a rational number** because it can be expressed as the quotient of two integers: 26 ÷ 1.

## Is 26 a whole number

**The first 100 whole numbers** are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25,26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74,

## What is ordinal number

We can use ordinal numbers to define their position. The numbers **1st(First), 2nd(Second), 3rd(Third), 4th(Fourth), 5th(Fifth), 6th(Sixth), 7th(Seventh), 8th(Eighth), 9th(Ninth) and 10th(Tenth)** tell the position of different floors in the building. Hence, all of them are ordinal numbers.

## What are types of numbers

**What does it look like?**

Type of Number | Example |
---|---|

Prime Number | P=2,3,5,7,11,13,17,… |

Composite Number | 4,6,8,9,10,12, |

Whole Numbers | W=0,1,2,3,4,… |

Integers | Z=…,−3,−2,−1,0,1,2,3,… |

## Are numbers irrational

**An irrational number is a number that cannot be written in the form of a common fraction of two integers. It is part of the set of real numbers alongside rational numbers. It can also be defined as the set of real numbers that are not rational numbers.Irrational numbers.**

π | = | 3.14159 |

e | = | 2.71828 |

= | 1.41421 |

## What is the factor of 26

The factors of 26 are **1, 2, 13 and 26**. As the number 26 is a composite number, it has more than two factors.

## Is an natural number

A natural number is **a number that occurs commonly and obviously in nature**. As such, it is a whole, non-negative number. The set of natural numbers, denoted N, can be defined in either of two ways: N = {0, 1, 2, 3, }

## What are set of integers

The set of integers consists of **zero (0), the positive natural numbers (1, 2, 3, ),** **also called whole numbers or counting numbers, and their additive inverses (the negative integers, i.e., −1, −2, −3, )**. The set of integers is often denoted by the boldface (Z) or blackboard bold.

## Is a decimal a rational number

Is Every Decimal Number Represented as a Rational Number? **No, every decimal number can not be represented as a rational number**. Non-terminating and non-repeating digits to the right of the decimal point cannot be expressed in the form p/q hence they are not rational numbers.

## Is a fraction an integer

**Fractions and decimals are not integers**. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers.

## What is number system and its type

The number system is simply **a system to represent or express numbers**. There are various types of number systems and the most commonly used ones are decimal number system, binary number system, octal number system, and hexadecimal number system.

## What are natural numbers in maths

Natural Numbers **The numbers that we use when we are counting or ordering** {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 …} Whole Numbers The numbers that include natural numbers and zero. Not a fraction or decimal.

## What type of number is a fraction

**Rational Numbers** These are any numbers that can be expressed as a fraction, which includes all integers and most decimals. Fractions are rational numbers so long as their bottom number (the denominator) is not zero, because dividing anything by zero is impossible. decimals that terminate or repeat.

## Which are co prime numbers

**Any two successive numbers/ integers** are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF. The sum of any two co-prime numbers are always co-prime with their product: 2 and 3 are co-prime and have 5 as their sum (2+3) and 6 as the product (2×3).

## Is 26 composite or prime

Yes, since 26 has more than two factors i.e. 1, 2, 13, 26. In other words, 26 is a **composite number** because 26 has more than 2 factors.

## Is 27 composite or prime

Yes, since 27 has more than two factors i.e. 1, 3, 9, 27. In other words, 27 is a **composite number** because 27 has more than 2 factors.

## Is 25 prime or composite

Is 25 a composite number? Yes. 25 is divisible by 5, so **it is composite**. The factors of 25 are 1, 5, and 25.
