To be fair to OP, these questions usually imply that the numbers have been quoted in such a way that one place is missing. In this case,
for the UB, the numerator needs to be as big as possible and the denominator as small as possible.
BTW, at GCSE (IMHO) trying to learn formula such as Formula UB=(UB-LB)^2 LB=(LB-UB)^2 is unnecessary, you are far better thinking about the fraction involved and about how you can make the UB (top-big bottom-small) or the LB (top-small bottom-big). Formulae are useful but sometimes serve as a barrier to understanding where formulae are invented to handle every possible situation.
Working for the LB is similar.Last edited by nerak99; 18-04-2016 at 13:45. Reason: Expan on answer
