Kua tāruatia ki te papatopenga
x+\frac{9}{20}x=145
Whakahekea te hautanga \frac{45}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{29}{20}x=145
Pahekotia te x me \frac{9}{20}x, ka \frac{29}{20}x.
x=145\times \frac{20}{29}
Me whakarea ngā taha e rua ki te \frac{20}{29}, te tau utu o \frac{29}{20}.
x=\frac{145\times 20}{29}
Tuhia te 145\times \frac{20}{29} hei hautanga kotahi.
x=\frac{2900}{29}
Whakareatia te 145 ki te 20, ka 2900.
x=100
Whakawehea te 2900 ki te 29, kia riro ko 100.
