Question

PLEASEEE HELP I HAVE NO IDEA ITS DUE IN 10 MIN

Answer 1

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:

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