Answer:

#g= 10 or g=1/10# depending on what is meant in the question,

Explanation:

It is not clear whether the question means:
#4 = (2g)/5 " "or" "4= 2/(5g)#

Let's consider both.

#4 = (2g)/5" "larr xx 5/2# on both sides

#4 xx5/2 = (2g)/5 xx 5/2#

#10 =g#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Or

#4= 2/(5g)" "larr#invert both sides

#1/4 = (5g)/2" "larr xx 2/5# on both sides

#1/4 xx2/5 = (5g)/2 xx 2/5#

#1/10 = g#
