Final answer:
To find the weight of each portion, divide the total weight of the trail mix (5/8 pound) by the number of portions (4). Each portion of the trail mix weighs 5/32 pound.
Step-by-step explanation:
To find the weight of each portion, we need to divide the total weight of the trail mix (5/8 pound) by the number of portions (4).
Dividing fractions is similar to multiplying by the reciprocal. So, we can multiply 5/8 by 1/4.
5/8 x 1/4 = 5/32
Therefore, each portion of the trail mix weighs 5/32 pound.
