For 1/3 it is 3/9 and 2/4 is 6/12
Answer:
Step-by-step explanation:
c
<u>Answer:</u>
3 and 60
<u>Step-by-step explanation:</u>
For the given proportions, 
, 3 and 60 are the extremes while 12 and 15 are the means.
To understand this, we can take a look at an example.
Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as
:
Here, a and d are the extreme ends and b and c are the means.
Length (L): w + 3.5
width (w): w
Perimeter (P) = 2L + 2w
31 = 2(w + 3.5) + 2(w)
31 = 2w + 7 + 2w
31 = 4w + 7
24 = 4w
6 = w
Length (L): w + 3.5 = (6) + 3.5 = 9.5
Answer: width = 6 inches, length = 9.5 inches
