Then add that number to the number of normal frogs to find the total number of frogs: 9 frogs + 18 frogs = 27 frogs. Finally, divide the number of mutant frogs by the total number of frogs and multiply by 100% to find the percentage of frogs that are mutants: 9 frogs / 27 frogs * 100% = 33.333...%, which rounds to 33%. Final answer: 33. <ibo> Nke mbụ, gbakọọ ọnụ ọgụgụ nke ụdị atọ nke igurube ndị gbanwere agbanwe: 5 igurube + 2 igurube + 2 igurube = 9 igurube.
