Of the students in Rosalies dance class 29 out of 59 have participated in dance class before. About how many of her students have participated in class before?
its 1/2 if anyone needs the answer.
"About how many " suggest to me that you want a quick approximate answer
well, isn't 29 close to 30 and isn't 59 close to 60
so, what is 30/60 in your head ???
