#2.4=2 2/5# (as a mixed fraction)
or #=12/5# (as an improper fraction)

Explanation:

#color(red)(2).color(blue)(4)# means #color(red)(2)xx10^0 + color(blue)(4)xx10^-1#

#= color(red)(2)xx1 + color(blue)(4)/10#

#=2 4/10 = 2 2/5#

The decimal point between the (in this case) #color(red)(2)# and the #color(blue)(4)# marks the beginning of the negative exponents for the #10#'s
