Kua tāruatia ki te papatopenga
15\times 16.45=7x
Me whakarea ngā taha e rua o te whārite ki te 105, arā, te tauraro pātahi he tino iti rawa te kitea o 7,15.
246.75=7x
Whakareatia te 15 ki te 16.45, ka 246.75.
7x=246.75
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{246.75}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{24675}{700}
Whakarohaina te \frac{246.75}{7} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{141}{4}
Whakahekea te hautanga \frac{24675}{700} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 175.
