Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction

21.192 can be written as 21 192/1000 so yes its rational

i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.

Hope this helps :P

To find out how many students voluteered, simply add the fractions:

$\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{2}{6}$

Remember that 2/6=1/3, so the sum is actually

$\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{3}$

We can sum the first and last terms immediately:

$\dfrac{2}{3}+\dfrac{1}{4}$

And finally, we can change both fractions so that they have the same denominator:

$\dfrac{2}{3}+\dfrac{1}{4} = \dfrac{8}{12}+\dfrac{3}{12} = \dfrac{11}{12}$
