Answer:
3 and 60
Step-by-step explanation:
For the given proportions, [tex] \frac { 3 } { 15 } = \frac { 12 } { 60 } [/tex], 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
:
[tex]ab=cd[/tex]
Here, a and d are the extreme ends and b and c are the means.
