If you dry fresh pears, then their weight will decrease by 80%. How much fresh pears will be needed to prepare 8 kg of dried pears?

Decision.
If the mass of pears is reduced by 80%, then
100% -80% = 20% – pear mass will remain after drying;
In our case, 20% is 8 kilograms.
(8kg / 20%) × 100% = (8kg × 100%) / 20% = (8 × 10) / 2 = 80/2 = 40 kg – you will need fresh pears to prepare 8 kg of dried pears.
Answer. 40 kilograms.
