Answer:
Option 4
Step-by-step explanation:
You divide 1/2 by the whole problem
5x-15=20
and go from there its too long to explain but its option 4
1. 2r-5
2. -21r-50
3. 4r-50
4. 14r+50
5. 19r-50
Ratio is a division in its simplest form.
To get the ratio of length to width, divide the two then simplify.
In this case, convert the length and width into decimals.
length = 7 1/2 = 7.5
width 4 3/4 = 4.75
ratio of length to width is;
7.5/4.75 = 750/475
This can now be written as;
750 : 475
Dividing both sides by 25;
= 750/25: 475/25
= 30 : 19
