Answer:

See the entire solution process below:

Explanation:

Multiply each side of the equation by #color(red)(36)# to solve for #x#:

#color(red)(36) xx 5/12 = color(red)(36) xx x/36#

#(3 xx 12) xx 5/12 = cancel(color(red)(36)) xx x/color(red)(cancel(color(black)(36)))#

#(3 xx color(red)(cancel(color(black)(12)))) xx 5/color(red)(cancel(color(black)(12))) = x#

#15 = x#

#x = 15#

and

#5/12 = 15/36#
