Rachel poured 4/5 of a gallon of water into a bucket. Later, she added 3/10 of a gallon more. How much water is in the bucket now?

1  1/10 gallons

Step-by-step explanation:

Add 4/5 gallon + 3/10 gallon

Get a common denominator of 10

4/5*2/2  + 3/10

8/10 +3/10

11/10

Change from an improper fraction to a mixed number

10/10 + 1/10

1 1/10 gallons

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
