Which one of these is the best value? My brain isn't working

[HKmummymoo]

Looking to buy something in liquid form and can't work out which is the best value, or how to work it out.

Normally I would find this really easy but 18 months of being off work with a baby has turned my brain to mush.

2250 gr £28
3250 gr £35
4500 gr £45
6000 gr £56.90

Believe it's the larger one but how do you work it out?

You divide the price by the number of grams to get price per gram, there's not a lot in it but the last one is the best value
£28/22500 = 1.2p a gram
£35/3250 = 1.1p a gram
£45/4500 = 1p a gram
££56.90/6000 = 0.95p a gram

definitely the largest (as usual )

2250 @ £28 = 1.24
3250 @ £35 = 1.07
4500 @ £45 = 1
6000 @ £56.90 = .948

Indigo beat me to it

Fab thank you! I'm very embarrassed I couldn't do that myself
