When solving problems where you convert ratios/proportions to percentages, you first want to add the parts to get the whole. In this case, we have 3 parts electric and 6 parts gas. 3 + 6 = 9, so there are 9 total parts. Then we divide the part we are interested in (in this case, gas which is 3) by the total number of parts (the whole, which is 9): ³/₉ = 0.33 = 33%
