The students at Norton School were asked to name their favorite type of pet. Of the 430 students surveyed, 258 said in that their favorite type of pet was a dog. Assume that only 100 students were surveyed, with same results, about how many students would say in which a dog is their favorite type of pet?

Finding what 100 students would say is the same as finding the percent, because percent means "out of 100." To find the percent, divide the number of students who said a dog was their favorite (258) by the total number of students surveyed (430); 258 ÷ 430 = 0.6. Change 0.6 to a percent through moving the decimal two places to the right. 60%. This means in which 60 out of 100 students would say dog.
