Sebastian's work. StartFraction part Over whole EndFraction = StartFraction 20 times 1 Over 160 times 1 EndFraction = StartFraction 20 Over 160.

Katarina's work. StartFraction part Over whole EndFraction = StartFraction 160 divided by 5 Over 100 divided by 5 EndFraction = StartFraction 32 Over 20 EndFraction

Eduardo's work. StartFraction part Over whole EndFraction = StartFraction 160 times 5 Over 100 times 5 EndFraction = StartFraction 800 Over 200 EndFraction
