Answer:

78

Explanation:

So, to solve this problem, we have to divide 117 by 3, because one third of the staff is going away. 117 divided by 3 equals 39, which is number of staff this is going away. Next we have to subtract 39 from 117, which will give us our answer. 117 - 39 = 78

Happy Holidays!

78 members are not traveling

Explanation

Step1

we need to use fractions to find the number of memebers are going away, so the whole number (117) is represented by 1

then,Let

whole number=full staff= 117

One third of them are going away for the Thanksgiving holiday, to find the number of members just do:(fraction by number)


\begin{gathered} \text{Members are going away=}(1)/(3)\cdot117 \\ \text{Members are going away=}39 \end{gathered}

Step 2

now, let's use subtraction to find the number of members that are not traveling


\begin{gathered} \text{Members are not traveling=full staff -member are going away} \\ \text{Members are not traveling=117-39} \\ \text{Members are not traveling=}78 \end{gathered}

I hope this helps you
