The pattern behind it: Dividing fractions
Share a fraction equally, or count how many small portions fit.
In this one. Dividing by a whole number makes the pieces smaller, so more of them fit in one litre — which is why the denominator is multiplied and the numerator is left alone.
How to spot it
A total amount split into fraction-sized cups or pieces, asking how many fit, points here. A single fraction shared equally among several parts does too.
Common mistake
Children expect dividing to make the answer smaller, so a bigger result than the starting amount looks wrong to them and they flip the calculation.
