2141357=x-x\times \frac{1}{10}
Whakahekea te hautanga \frac{10}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
2141357=\frac{9}{10}x
Pahekotia te x me -x\times \frac{1}{10}, ka \frac{9}{10}x.
\frac{9}{10}x=2141357
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=2141357\times \frac{10}{9}
Me whakarea ngā taha e rua ki te \frac{10}{9}, te tau utu o \frac{9}{10}.
x=\frac{2141357\times 10}{9}
Tuhia te 2141357\times \frac{10}{9} hei hautanga kotahi.
x=\frac{21413570}{9}
Whakareatia te 2141357 ki te 10, ka 21413570.
