When solving for best value, either change all the prices to fit 1 item, or find a HCF between the options and change the prices to fit that amount of items
When solving using integer scaling, find the scale factor and divide both sides to fit the new value, or divide the old values by 1 and multiply them to fit the question.
e.g.
108l £125.28 £125.28/108 = 1.16
| /4 | /4 or 1.16 x 27 = £31.32
27l £31.32
