Step-by-step explanation:</h2>
We need to think, 28 / 42 = x / 54.
We need to do a proportion for this problem!
First, line up both fractions, then put a equal sign between both fractions.
28 / 42 = x / 54.
We multiply in a diagonal and then we divide by the one without a diagonal.
28 and 54 are a diagonal.
We multiply both numbers!
54 x 28 = 1,512.
Then, we divide by 42.
1,512 / 42 = 36.
Therefore, x = 36.

Good luck!
Dividing the line segment AB into ratio 1:3 or 3:1 means dividing the line segment into four equal lengths, as shown in the diagram below.
Point P is the point that divides the line into 1 part and 3 parts, from A.
Point Q is the point that divides the line into 1 part and 3 parts, from B
Hence, P and Q are points on different position

Let's work out the process to find the numerator:
(x+2)/2 - (x+1)/3x Factor using the LCD, 6x
3x(x+2)/6x - 2(x+1)/6x
(3x² + 6x - 2x - 2)/6x
= (3x² + 4x - 2)/6x
Answer is 3x² + 4x - 2
Hopefully I did this correct, Not to good with math c':
