g

StartFraction 1.98 Over 11 + g EndFraction minus StartFraction 12 Over 100 EndFraction = 1

StartFraction 1.98 Over 11 + g EndFraction + StartFraction 12 Over 100 EndFraction = 1

StartFraction 11 + g Over 1.98 EndFraction = StartFraction 12 Over 100 EndFraction

StartFraction 1.98 Over 11 + g EndFraction = StartFraction 12 Over 100 EndFraction
