#63/5#

Full explanation given. Once you are used to these you can do them in very few lines.

Explanation:

#color(blue)("Just a thought to consider")#

Before we start did you know that, although not normally done, you can write for example: #1,2,3,4,5# and so on as #1/1,2/1,3/1,4/1,5/1 # and so on.

#color(blue)("Answering the question")#

Write as #12+3/5#

#color(brown)("Consider just the 12 part.")#

Multiply by 1 and you do not change the value. However, 1 comes in many forms.

#color(green)(12color(red)(xx1) color(white)("dddd") ->color(white)("dddd") 12color(red)(xx5/5) #

#color(green)( color(white)("ddddddddd") ->color(white)("dddd") 12/1color(red)(xx5/5) #

#color(green)( color(white)("ddddddddd") ->color(white)("dddd") (12 color(red)(xx5) )/(1color(red)(xx5)) = 60/5) #

#color(brown)("Putting it all back together")#

#12+3/5 color(white)("dddd") ->color(white)("dddd")60/5+3/5#

#color(white)("dddddddddd")->color(white)("dddd")(60+3)/5#

#color(white)("dddddddddd")->color(white)("ddd.dd")63/5#
