Cdef maps to jklm with the transformations (x, y) --> (5x, 5y) --> (x-4, y-4). what is the value of ef/lm?

Given that CDEF maps to JKLM ,with the transformation (x, y) ---> (5x, 5y) ---> (x - 4, y - 4).

This means that each part of CDEF is increased by a factor of 5 and then moved 4 places to the left to get JKLM.

Thus, the ratio of any part of CDEF to the corresponding part in JKLM is 1 : 5.

Therefore, EF / LM = 1 / 5.
