\frac{550}{125}=\frac{x}{2.75}
Whakarohaina te \frac{5.5}{1.25} mā te whakarea i te taurunga me te tauraro ki te 100.
\frac{22}{5}=\frac{x}{2.75}
Whakahekea te hautanga \frac{550}{125} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
\frac{x}{2.75}=\frac{22}{5}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{22}{5}\times 2.75
Me whakarea ngā taha e rua ki te 2.75.
x=\frac{22}{5}\times \frac{11}{4}
Me tahuri ki tau ā-ira 2.75 ki te hautau \frac{275}{100}. Whakahekea te hautanga \frac{275}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
x=\frac{22\times 11}{5\times 4}
Me whakarea te \frac{22}{5} ki te \frac{11}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{242}{20}
Mahia ngā whakarea i roto i te hautanga \frac{22\times 11}{5\times 4}.
x=\frac{121}{10}
Whakahekea te hautanga \frac{242}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
