Kua tāruatia ki te papatopenga
\frac{9}{10}x=45
Whakahekea te hautanga \frac{90}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
x=45\times \frac{10}{9}
Me whakarea ngā taha e rua ki te \frac{10}{9}, te tau utu o \frac{9}{10}.
x=\frac{45\times 10}{9}
Tuhia te 45\times \frac{10}{9} hei hautanga kotahi.
x=\frac{450}{9}
Whakareatia te 45 ki te 10, ka 450.
x=50
Whakawehea te 450 ki te 9, kia riro ko 50.
