8 + x

StartFraction 0.8 Over 8 + x EndFraction times StartFraction 5 Over 100 EndFraction = 1
StartFraction 0.8 Over 8 + x EndFraction times = StartFraction 5 Over 100 EndFraction
StartFraction 0.8 Over 8 + x EndFraction = StartFraction 100 Over 5 EndFraction
StartFraction 0.8 Over 8 + x EndFraction divided by StartFraction 5 Over 100 EndFraction = 1
