\frac{11200}{10000}=1+\frac{x}{100}
Whakawehea ngā taha e rua ki te 10000.
\frac{28}{25}=1+\frac{x}{100}
Whakahekea te hautanga \frac{11200}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 400.
112=100+x
Me whakarea ngā taha e rua o te whārite ki te 100, arā, te tauraro pātahi he tino iti rawa te kitea o 25,100.
100+x=112
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=112-100
Tangohia te 100 mai i ngā taha e rua.
x=12
Tangohia te 100 i te 112, ka 12.
