Rational numbers
A) $\sqrt { 7 } , \sqrt { 16 }$
B) $12 , - 23,0 , \frac { 0 } { 2 } , \sqrt { 16 } , 0.18$
C) $12,0 , \sqrt { 16 }$
D) $\sqrt { 7 } , \frac { 0 } { 2 } , 0.18$

Question

Quizplus · Accepted Answer

Rational numbers are numbers that can be expressed as a fraction of two integers. In set B, $12, -23, 0, \frac{0}{2}, \sqrt{16}, 0.18$ are rational because: $12, -23, 0$ are integers (and all integers are rational), $\frac{0}{2} = 0$ (which is rational), $\sqrt{16} = 4$ (which is an integer and thus rational), and $0.18$ can be expressed as a fraction $\frac{18}{100}$.
