Question

a hiking club leader asked the beginner and advanced groups where they would prefer to go hiking.
hiking preference
forest trail marsh trail
beginner 5 8
advanced 7 3
what fraction of the advanced group want to hike on the marsh trail?
$\frac{3}{11}$ $\frac{11}{23}$ $\frac{3}{23}$ $\frac{3}{10}$

Explanation:

Step1: Find total number of advanced - group members

Add the number of advanced - group members who prefer forest trail and marsh trail. $7 + 3=10$.

Step2: Calculate the fraction

The number of advanced - group members who want to hike on the marsh trail is 3. The fraction is $\frac{\text{Number of advanced on marsh trail}}{\text{Total number of advanced members}}=\frac{3}{10}$.

Answer:

$\frac{3}{10}$
