In gloria’s class about 25% of the students wore sweatshirts to school one day. if there are 29 students in her class, about how many students did not wear sweatshirts to school that day?

Okay so 29 students is 100% of the class, if only 25% wore sweatshirts that means the remaining did not so 100%-25%=75%. We want to convert that percentage to a decimal to multiply so 75% is the same as 0.75, multiply that by 29 and we get 21.75, depending on how the teacher or question wants it we will say about 22 students did not wear them as we rounded up

It is important because sometimes ur dna needs to multiply
