55-20 = 35

-----------------

B=Bill=55

G=Gas=35

E=Electricity=20

Ratio was:

35 : 20 = 7 : 4

as G : E = G÷5 : E÷5

So total (G+E) is (=) 55
G+E=55
E=20
G+20=55
G+20-20=55-20
G=35
G:E
35:20
simplify
35:20 can be thought of as a fraction so
35:20 =35/20
factor out the 5 in each (35=7*5, 20=4*5) sp 35/20=5/5 times 5/4
7:4=G:E
