Answer :
Final answer:
The location of the scuba diver in relation to sea level was -22 1/60 feet after descending 18 5/12 feet and then an additional 3 3/5 feet. This problem involves finding a common denominator and adding fractions and mixed numbers.
Explanation:
This is a problem related to adding fractions and mixed numbers. Let's start with the numbers given: 18 5/12 feet and 3 3/5 feet. The first thing we notice is that the fractions have different denominators, so to add them together, we first need to find a common denominator. The common denominator of 12 and 5 is 60. So we convert these fractions to have the same denominator: 18 5/12 becomes 18 25/60 and 3 3/5 becomes 3 36/60. When we add these together, we get 21 61/60. We simplify this mixed number by taking the extra 60/60 and adding 1 to the whole number. This gives us 22 1/60. Since the diver is descending, the number is negative. Therefore, the location of the scuba diver in relation to sea level was -22 1/60 feet. So the correct answer is option A.

Answer:
A. -22 1/60 feet
Step-by-step explanation:
So we know that the scuba diver descended 18 5/12 feet below sea level, and then descended another 3 3/5 feet. What we can do is first, add the whole numbers.
18 + 3 = 21
so we got the whole numbers out of the way for now. Now, we just need to focus on the fractions. If you look at the denominators (bottom numbers), you can see that they are different. What we need to do is make them the same, so we have to find the lowest common denominators, which would be 60. Here is how we do the math to find the LCD:
First, let's start with the 5/12, and remember, whatever you do to the denominator, you have to do to the numerator.
We have to multiply 12 by whatever makes it 60, which is 5.
12 * 5 = 60
And we have to do the same to the numerator
5 * 5 = 25
So now we have a fraction of 25/60. Let's move on to the next fraction, 3/5. The only way to get 5 to 60 is by multiplying it by 12.
5 * 12 = 60
And, again, the same for the numerator
3 * 12 = 36
So now we have 36/60 and 25/60. Now, we can finally add them. Since the denominators are the same number, we don't have to add them. Only the numerators.
36 + 25 = 61
We get 61/60, and because we cannot leave that undone, we make 1 whole number from that, leaving us with 22 1/60.
And because it is BELOW sea level, we make it negative, therefore we have -22 1/60
