Ratios and fractions are interchangeable (for the most part). A fraction is a type of ratio. And we've all worked with fractions before, so that's what we'll do here.
I can say that the ratio 3:1 is the same as the fraction 3 / 1. Using that fraction, it is fairly easy to find equivalent fractions.
3 / 1 = 6 / 2 = 9 / 3 = 30 / 10
...And so on
Another example, 5:6 = 5 / 6.
5 / 6 = 10 / 12 = 15 / 18 = 30 / 36
To find equivalent fractions, all you need to do is multiply both the numerator and denominator by the same number. As long as that number is the same (and your multiplication is correct), then the new fraction will be equivalent to the original.
Hope this helps!

Answer:
r = Q/(8s^2)
Step-by-step explanation:
Divide by the coefficient of r.
Q/(8s^2) = 8rs^2/(8s^2) = r
Answer:
A. 7.2 centimeters
Step-by-step explanation:
The length of the base is 7.2 centimeters. The area of a rectangle is length*width
The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.
The working is as follows :
Area = 90 cm²
Height = 12.5 cm
Length = ?
<em>Length</em><em> </em><em>=</em><em> </em><em>Area</em><em> </em><em>÷</em><em> </em><em>Height</em>
<em>=</em><em> </em><em>90</em><em> </em><em>÷</em><em> </em><em>12</em><em>.</em><em>5</em>
<em>=</em><em> </em><em>7.2cm</em>
