Как найти процент с помощью пропорции

{$ calc0.arg1|number:round $}% от числа {$ (calc0.arg2)|number:round $} = {$ (calc0.result || 0)|number:round $}

Число {$ (calc1.arg1)|number:round $} от числа {$ (calc1.arg2)|number:round $} = {$ (calc1.result || 0)|number:round $}%

{$ (calc2.arg2)|number:round $} плюс {$ calc2.arg1 $}% = {$ (calc2.result || 0)|number:round $}

{$ (calc3.arg2)|number:round $} минус {$ calc3.arg1 $}% = {$ (calc3.result || 0)|number:round $}

Число {$ (calc4.arg1)|number:round $} меньше числа {$ (calc4.arg2)|number:round $} на {$ (calc4.result || 0)|number:round $}%

Число {$ (calc5.arg1)|number:round $} больше числа {$ (calc5.arg2)|number:round $} на {$ (calc5.result || 0)|number:round $}%

Разница между числом {$ (calc6.arg1)|number:round $} и числом {$ (calc6.arg2)|number:round $} = {$ (calc6.result || 0)|number:round $}%

{$ (calc7.result || 0)|number:round $} составит 100%

x = {$ (calc8.result || 0)|number:round $}%
