For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is: , and then multiply our decimal answer by 100 to get the percentage: = 0.34 0.34 x 100 = 34 Therefore 34% of the students walk to school. I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))
