Hi,
Two Similar Triangles have a scale factor of 2/3. 
If the longest side of the smaller triangle is 15 inches, 
determine the length 'x' of the longest side of the larger triangle
 {{{2/3 = 15in/x}}}   |Cross Multiplying to solve
 {{{2x = 3*15in}}}
     x = 3*15in/2 = 22.5in  
CHECKING our answer***
 {{{15/(45/2)= 30/45 = 2/3}}}
