Larissa asked 40 students to name their favorite food. 10 students said their favorite food was pizza. what percent of the students survayed said their favorite food was pizza?

The answer would be 25% or 1/4 if you wanted it in fraction form. 

The percent of the students surveyed said their favorite food was pizza is 25%. You can simplify 10/40 by 10/10 which gives you 1/4. You then multiply 1/4 to a number that gives you ?/100, which would be 25/100. And that would give you 25%.
