There is a net loss of 2 glasses (2g) after the pour and refill. The container went from 4/5 full to 3/4 full.
4/5 - 3/4 = 2g... multiply across by 20
16 - 15 = 40g
1 = 40g ... The whole container full contained 40 glasses
4/5 - 3/4 = 2g... multiply across by 20
16 - 15 = 40g
1 = 40g ... The whole container full contained 40 glasses
