It is an irrational number.

Irrational numbers can be written as a decimal but not a fraction. It has an endless non-repeating digits to the right of the decimal point.

Rational numbers are those that can be written as a ratio. Meaning it can be written as a fraction where both numerator and denominator are whole numbers.

Please solve this question. ​

<h3><u>Answer</u> :</h3>

Let numerator of fraction be x and denominator be y.

∴ Fraction = x/y

★ <u>Part - A</u> :

:\implies\tt\:\dfrac{x\times 4}{y-2}=2

:\implies\tt\:4x=2(y-2)

:\implies\tt\:4x=2y-4

:\implies\tt\:2y=4x+4

:\implies\bf\:y=2x+2\:\:\dots (1)

★ <u>Part</u><u> </u><u>-</u><u> </u><u>B</u> :

:\implies\tt\:\dfrac{x+15}{2y-2}=\dfrac{9}{7}

:\implies\tt\:7(x+15)=9(2y-2)

:\implies\tt\:7x+105=18y-18

From equation (1)...

:\implies\tt\:7x+105=18(2x+2)-18

:\implies\tt\:7x+105=36x+38-18

:\implies\tt\:29x=105-18

:\implies\tt\:x=\dfrac{87}{29}

:\implies\boxed{\bf{x=3}}

:\implies\tt\:y=2x+2

:\implies\tt\:y=2(3)+2

:\implies\boxed{\bf{y=8}}

∴ Fraction = x/y = 3/8
