Whenever you have quantities or measurements in two opposing directions, you can label one of them as positive, the other as negative. One clear example is money - you can have money (positive), or you can owe money (negative). Your amount of money in a given month can increase (positive), or it can decrease (a "negative increase"). Another example is altitude above sea level - when you are BELOW sea level, you can use a negative number to express your "altitude above sea level". As to "rational" - most countries use a main currency (for example, U.S. dollar) and a fractional part thereof (for example, cents). Similarly, the altitude above sea levels is usually expressed in meters; but you can express smaller increments in fractions or decimals.
Negative rational numbers are used in the same way that negative whole numbers are used: they are simply the additive inverses of their positive counterparts.
There are multiple uses and application of negative numbers. They are used on a daily basis when describing temperature and in banking. For example, an overdrawn balance will be reported in negative amounts.
Counting your money would be one way.

'I've usually seen them in rational numbers and fractions oh and also in the instrument used to find out the temperature sorry i can't remember the name of the instrument.
The numbers called that are used in exponents can be called as a power of a number. The power or exponent can be positive , negative , zero .
Rational numbers are used in a hospital setting to prescribe dosage of drugs.
The letter R was used for real numbers. So Q, for quotients was used for rational numbers.
Rational numbers are numbers which can be written in the form p/q where p and q are integers and q > 0. Rationals is often used as an abbreviation to refer to the set of all rational numbers.
Negative numbers can be used for weather, when we talk about temperature that is below zero.
A rational number is a number that can be written in the form a/b, where "a" and "b" are integers and b is not equal to zero. For example, whole numbers are rational numbers.
Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.
