can you explain? thank you
Answer:
No, the reasoning is not correct.
Step-by-step explanation:
1. To get the correct answer, Akeem should first translate 1L into mL.
1L = 1000mL.
2. We now have the numbers 270mL and 1000mL. (Note: Even though 270 and 1000 aren't equal, we can go with the question.)
3. 270/1000 is how we describe the ratio before it's simplified.
4. Simplify.
270/1000 → divide 10 from both sides to start simplifying. → 27/100
We can't simplify anymore without going into decimals.
5. The correct answer would be 27:100.
Keep in mind that whenever you have a variable inside an expression, you have to think of it as a placeholder, hiding a certain value which we haven't specified yet.
Expressions with variables are a mean to express the generic idea underneath the expression, rather than its particular value.
So, an expression like x-7 represents the idea of subtracting 7 from a particular number. Once you give a specific value to x, the expression will become an actual subtraction between numbers, and you will be able to compute its value.
So, we have several values for x, which are several ways to turn our "abstract" subtraction into an actual, computable subtraction.

Answer:
=1050 wildebeests
Step-by-step explanation:
We can form an arithmetic series for the wildebeest migration.
Sₙ=n/2(2a+(n-1)d) where n is the number of terms, d is the common difference and a is the first term.
a=24
n=20
d=3
Sₙ=(20/2)(2(24)+(20-1)3)
Sₙ=10(48+57)
=1050 wildebeests
