Step-by-step explanation:
(I) A number which can be expressed in the form m/n, where m and n are integers and n is not equal to zero, is called a <u>Rational</u><u> Number</u><u> </u> .
(ii) If the integers m and n have no common divisor other than 1 and n is positive, then the rational number m/n is said to be in the <u>Simplest</u><u> form</u><u> </u>.
(iii) Two rational numbers are said to be equal, if they have the same <u>Simplest</u><u> </u><u>form </u><u>.</u>
(iv) If m is a common divisor of x and y, then x/y = (x ÷ k)/<u>(</u><u> </u><u>y </u><u>÷</u><u> </u><u>k)</u><u> </u> .
(v) The standard form of -1 is <u>-</u><u>1</u><u>/</u><u>1</u><u> </u>
(vi) If m/n is a rational number, then n cannot be <u>0</u><u> </u>
(vii) Two rational numbers with different numerators are equal, if their numerators are in the same <u>ratio </u>as their denominators.
