<span>Division or multiplication a ratio factors by a common factor results in an equivalent ratio. Thus, equivalent ratios to 20 / 15 include: (20/5) / (15/5) = 4 / 3, (20 x 1.2) / (15 x 1.2) = 24 / 18, (20 x 2) / (15 x 2) = 40 / 30. Therefore, three equivalent ratios to 20 / 15 are: 4 / 3, 24 / 18, 40 / 30 etc

Answer:
$57.75
Step-by-step explanation:
If 11 books cost $42.35,
11b=42.35
b=42.35/11
b=3.85
15 books will cost 15b.
15b
= 15*3.85
= 57.75.
15 Books will cost $57.75.
This in the simplest form will be 2/15. You cannot divide this answer by anything which means it is in its simplest form!

Answer:
144 square feet
Step-by-step explanation:
The 12-foot width apparently includes the garden and path, so the desired area is that of a 12-foot square:
A = s² = (12 ft)² = 144 ft²
The area of the garden and path is 144 square feet.
Draw a line through the x axis at x=3 and shade in everything to the left of x=3. That is your graph.
