you have to find the upper and lower bound of each number.
lb of 1470 litres (nearest 5 litres) = 1465
ub = 1475
lb of 288.2ml (one dp) = 288.15
ub = 288.25
to find the no of full tins you have to divide the volume of the soup by the volume of the tins
to find the MAXIMUM volume you have to try and get the largest number possible so you have to divide your UPPER BOUND by your LOWER BOUND as this will give u the largest value possible.
UB/LB
= 1475/ 288.15
= 5.118861704
round down (FULL tins)
= 5 tins
