S 5 34 425 Squareroot 3 08 pi 132 Squareroot 31 List the s

S = {-5, -3/4, 4.25, - Squareroot 3, 0.8, pi, 13/2, Squareroot 31} List the subset of S consisting of rational numbers. Select one: {-5, -3/4, 4.25, 0.8, 13/2} {-5, -3/4, 4.25, 0.3, 13/2, 13/2, Squareroot 81} {-5, -3/4, 4.25, 0.8, pi, 13/2, Squareroot 81} {-5, -3/4, 4.25, 0.8, pi, 13/2}

Solution

Rational number - all rational number can be represented in the form of p/q , where p and q both are integer and p/q not equal to zero

therefore option B is correct

s ={-5,-3/4,4.25, 0.8,13/2,sqrt(81)}

sqrt(81) also an rational number = 9
