if p is equal to minus 2 upon 3 and q is equal to 9 upon 20 verify the following properties p+q#q-p
Answers
Answer:
A number that can be expressed in the form p/q, where p and q are integers and q ≠ 0, is called a rational number. All integers and fractions are rational numbers.
Examples: -2/7, 3/8, etc.
Numerator and denominator
In p/q, the integer p is the numerator, and the integer q (≠ 0) is the denominator.
Explanation:
numerator and denominator of a rational number by the same non zero integer, we obtain another rational number equivalent to the given rational number.
Positive rational numbers: When the numerator and denominator both are positive
negative rational numbers: When the numerator is positive and denominator is negative.
The number 0 is neither a positive nor a negative rational number.
Subsequently, the concept of rational numbers on a number line is also explained.
After this, in the first half of the chapter, some more topics like rational numbers in standard form, comparison of rational numbers and rational numbers between two rational numbers are explained.
