There should be two characteristics that we look at the numbers when grouping them.
The first one is their signal, if they are positive, or negative.
The second one is if they are decimal, or not.
Looking at these characteristics, we can see the sets in which they belong.
Lowest Common Denominator refers to lowes t common multiple. These expressions have two terms 'x' and 'y' and we want to choose the expression that has the highest power such that the other expressions can be multiplied into the common denominator.
For the 'x' term, the highest power is x⁴ and for the 'y' term, the highest power is y⁵
Common denominator of A, B, C, and D: x⁴y⁵
The answer is 
Let's build the expression piece by piece, translating sentences into formulas:
"3/5 times..." 
"5 less than a number..." 
So, the first block becomes
"3/5 times 5 less than a number..." 
"...is no more than 27" 
So, putting the pieces together, you have the answer
Answer:
1,100
Step-by-step explanation:
Since we know that 825 people are men, and that 75% of the people are men, we can write an equation to help us solve this, which is x times 0.75= 825, with x representing how many people work at the company. We must divide both sides by 0.75 to isolate the variable x and get our answer, which is 1,100 as x= 1,100 (825 divided by 0.75 equals 1,100).
