Kua tāruatia ki te papatopenga
\frac{27}{80}\times 120=x
Me whakarea ngā taha e rua ki te 120.
\frac{27\times 120}{80}=x
Tuhia te \frac{27}{80}\times 120 hei hautanga kotahi.
\frac{3240}{80}=x
Whakareatia te 27 ki te 120, ka 3240.
\frac{81}{2}=x
Whakahekea te hautanga \frac{3240}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.
x=\frac{81}{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
