asked by Sheila
  1. total number of students on the bus = 46
    so what is the percentage equivalent of 20/46 ?
    You just want an approximation.
    If it had been 20/50 it would have been 40%
    you the denominator is a bit less than 50, so your
    percentage is a bit more than 40%,
    How about 43% or 44% ?
