Answer:
Samuel slept for 1/4 of the distance.
Step-by-step explanation:
The information provided are:
- Samuel fell asleep halfway home.
- He didn't wake up until he still had half as far to go as he had already
- gone while asleep.
Consider that the total distance covered was 1.
Then from the first point we know that Samuel fell asleep after covering a distance of 1/2.
It is provided that he woke up only after covering half of the remaining distance.
That is, he slept for 1/4 of the remaining distance.
Thus, Samuel was asleep for 1/4th of the entire trip home.

Answer:
Step-by-step explanation:
Given the following expression:
Find the Greatest Common Factor (GCF) of the numerator. The steps to do this are:
1. You need to descompose into prime factors:
2. Now you must choose the common ones with the lowest exponents and multiply them. In this case the common one is 2 and its lowest exponent is 1, then:
Knowing this, you can factor out the Greatest Common Factor (GCF) in the numerator:
Finally, simplifying, you get:
Answer: B
Step-by-step explanation:
Let's work this problem backwards. So, if he has y dollars left after spending 25% the second time or 3/4 of the money left. So, inverse it to get y. Then, do the same for 20% or 4/5, then 4/3y * 5/4 = 5/3y
