x+3.5=\frac{13.2}{0.4}
Whakawehea ngā taha e rua ki te 0.4.
x+3.5=\frac{132}{4}
Whakarohaina te \frac{13.2}{0.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x+3.5=33
Whakawehea te 132 ki te 4, kia riro ko 33.
x=33-3.5
Tangohia te 3.5 mai i ngā taha e rua.
x=29.5
Tangohia te 3.5 i te 33, ka 29.5.
