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 2 "parts" sheep and 5 "parts" other animals. 2 + 5 = 7, so there are 7 total "parts". Then we divide the part we are interested in by the total numbers of "parts" (the whole): ²/7 = 0.29 = 29%
