Standard Form of Rational Numbers
Standard Form of Rational Numbers:
A rational number is said to be in the standard form, if its denominator is a positive integer and the numerator and denominator have no common factor other than 1.
Example: Express -9/24 in standard form.
Solution: (-9)/24
The denominator of the rational number −9/24
is positive. In order to express it in standard form, we divide its numerator and denominator by the greatest common divisor of 9 and 24 is 3.
Dividing the numerator and denominator of −9/24
by 3, we get
−9/24
= [(−9)÷3]/[24÷3] = −3/8
Thus, the standard form of −9/24 is −3/8
