\frac{ϕ\times \frac{4+1}{4}\times 7}{\frac{12\times 12+7}{12}-\frac{11\times 3+1}{3}}

Méadaigh 1 agus 4 chun 4 a fháil.

\frac{ϕ\times \frac{5}{4}\times 7}{\frac{12\times 12+7}{12}-\frac{11\times 3+1}{3}}

Suimigh 4 agus 1 chun 5 a fháil.

\frac{ϕ\times \frac{5\times 7}{4}}{\frac{12\times 12+7}{12}-\frac{11\times 3+1}{3}}

Scríobh \frac{5}{4}\times 7 mar chodán aonair.

\frac{ϕ\times \frac{35}{4}}{\frac{12\times 12+7}{12}-\frac{11\times 3+1}{3}}

Méadaigh 5 agus 7 chun 35 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{144+7}{12}-\frac{11\times 3+1}{3}}

Méadaigh 12 agus 12 chun 144 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{151}{12}-\frac{11\times 3+1}{3}}

Suimigh 144 agus 7 chun 151 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{151}{12}-\frac{33+1}{3}}

Méadaigh 11 agus 3 chun 33 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{151}{12}-\frac{34}{3}}

Suimigh 33 agus 1 chun 34 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{151}{12}-\frac{136}{12}}

Is é an t-iolrach is lú coitianta de 12 agus 3 ná 12. Coinbhéartaigh \frac{151}{12} agus \frac{34}{3} chuig codáin a bhfuil an t-ainmneoir 12 acu.

\frac{ϕ\times \frac{35}{4}}{\frac{151-136}{12}}

Tá an t-ainmneoir céanna ag \frac{151}{12} agus \frac{136}{12} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.

\frac{ϕ\times \frac{35}{4}}{\frac{15}{12}}

Dealaigh 136 ó 151 chun 15 a fháil.

\frac{ϕ\times \frac{35}{4}}{\frac{5}{4}}

Laghdaigh an codán \frac{15}{12} chuig na téarmaí is ísle trí 3 a bhaint agus a chealú.

\frac{ϕ\times \frac{35}{4}\times 4}{5}

Roinn ϕ\times \frac{35}{4} faoi \frac{5}{4} trí ϕ\times \frac{35}{4} a mhéadú faoi dheilín \frac{5}{4}.

\frac{ϕ\times 35}{5}

Cealaigh 4 agus 4.

ϕ\times 7

Roinn ϕ\times 35 faoi 5 chun ϕ\times 7 a fháil.
