-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.

The antelope is faster than the wildebeest.
Step-by-step explanation:
The maximum recorded speed for the antelope is 88.5 km/h that it can sustain for almost a kilometer.
The equation for distance a wildebeest can run in t hours is given as ;
d=80t
Assume t=1 hour,d=80*1=80 km then you can say the wildebeest takes 1 hour to cover 80 km and 80 km/h
For a distance of 80 km, the antelope will take how many hours;
Time =Distance/speed =80/88.5 =0.904 hours
The antelope takes less hours to cover the distance, hence the antelope is faster than the wildebeest.
