The number 91 is a rational number, an integer, a natural number, a real number, and a whole number.

Explicação

## Step 1<br />The number 91 is a rational number. A rational number is any number that can be expressed as the quotient or fraction \( \frac{p}{q} \) of two integers, where \( p \) is the numerator and \( q \) is the denominator, and \( q \) is not zero. Since 91 can be expressed as \( \frac{91}{1} \), it is a rational number.<br /><br />## Step 2<br />The number 91 is an integer. Integers include all whole numbers and their negative counterparts, but no fractions or decimals. Since 91 is a whole number, it is also an integer.<br /><br />## Step 3<br />The number 91 is a natural number. Natural numbers are a part of the number system which includes all the positive integers from 1 to infinity. Since 91 is a positive integer, it is a natural number.<br /><br />## Step 4<br />The number 91 is a real number. Real numbers include all the numbers that can be found on the number line. This includes both rational and irrational numbers. Since 91 is a rational number, it is also a real number.<br /><br />## Step 5<br />The number 91 is not an irrational number. Irrational numbers are numbers that cannot be expressed as a fraction \( \frac{p}{q} \) for any integers \( p \) and \( q \). Since 91 can be expressed as \( \frac{91}{1} \), it is not an irrational number.<br /><br />## Step 6<br />The number 91 is a whole number. Whole numbers are a part of the number system which includes all the natural numbers along with zero. Since 91 is a natural number, it is also a whole number.
