Let x = number of students in each of the remaining rows

266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13

10 x 20 = 200
5 x 8 = 40 

266 - (200 + 40) = 26

26 ÷ 2 = 13students

-25 is an integer and a rational number.

<h3>What is number system?</h3>
  • A system of writing numbers is known as a number system.
  • It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set.
  • It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.

Now,

  • Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.
  • A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.
  • Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.
  • Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.
  • A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.

Hence, -25 is an integer and a rational number.
