Step-by-step explanation:
If Levi has $30, and he spends 1/5 of it on his movie ticket, we can figure out how much 1/5 is by dividing 30 by 5.
30 divided by 5 = 6
Now Levi has $6. He than spends 1/3 of that on popcorn. We can divide 6 by 3.
6 divided by 3 = 2
Levi is left with $2.

Answer:
The fraction of trip completed by Andre is
km
Step-by-step explanation:
Given as :
The Total distance between the home to a festival = 1
km
I.e The total distance between the home to a festival =
km
The distance cover by Andre before taking rest =
km
Let The fraction of trip completed by Andre = x km
So, <u>According to question</u>
The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest
or, x =
km -
km
or, x =
km
∴ x =
km
Or, The fraction of trip completed by Andre = x =
km
Hence , The fraction of trip completed by Andre is
km Answer
