plssss Anss.......
ayushree goal is to practice 20 minutes of maths for every 60 minutes of class time how many minutes of maths practice should she do if the class is 90 M long??


plss ans plss it's urgent.....

Answer 1

given - 60 min of class she can practise 20 mins of maths

so 60 min = 20 min of work

 then 1 min  = 20 / 60

you get 1/3

therefore, 90 min = 90* 1/3

                              =30 min -( she does maths in the class)
