how do I help my son answer this question/ cary spent 1/3 of his class working on fraction problems and 3/6 of his class working on algebra problems. He spent the last 10 minutes of his class reading a chapter in his textbook. How many minutes long was the entire class? Thank you for your help I did not do good in school and I want him to do better.
let T be the entire class time.
1/3 T + 3/6 T + 10=T
