Question

Every point on a number line represents with solutions(a)a unique real number (b) a natural number (c) a rational number (d) an irrational number

Answer 1

[ (a) A unique real number ]

Every point on a number line represents with solution a unique real number .

• Real numbers

All the numbers including whole numbers which start from zero to infinity , natural numbers which start from 1 to infinity , rationals in p by Q form , irrational numbers which are non terminating and non recurring , integers which are number of positive numbers with zero and their negatives all come under real numbers .

• Natural numbers

We have mention that has numbers are the numbers which start from 1 and end with infinity . So any number which is Mark the number line on zero or negative dance it cannot be a natural number . So second option is incorrect .

• Rational and irrational numbers

We noted that rational numbers of the numbers which can be written in p by Q form where p and q are integers Q is not equal to zero . If any number like an irrational number which is negative or in any other forms cannot be considered on number line . So last two options are also incorrect .

Hence the answer is justified to be (A)

• Natural number - Counting number are called natural number. 1 is the smallest natural number.
• A rational number - Number that can be represented as p/q form are called rational number.
• An irrational number - Number that can not be represented as p/q form is called irrational number.
• Whole number- Number from 0 to infinite are called whole number. 0 is the smallest whole number.
