\frac{x}{2.2}=\frac{25}{22}
Whakahekea te hautanga \frac{100}{88} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
x=\frac{25}{22}\times 2.2
Me whakarea ngā taha e rua ki te 2.2.
x=\frac{25}{22}\times \frac{11}{5}
Me tahuri ki tau ā-ira 2.2 ki te hautau \frac{22}{10}. Whakahekea te hautanga \frac{22}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{25\times 11}{22\times 5}
Me whakarea te \frac{25}{22} ki te \frac{11}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{275}{110}
Mahia ngā whakarea i roto i te hautanga \frac{25\times 11}{22\times 5}.
x=\frac{5}{2}
Whakahekea te hautanga \frac{275}{110} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 55.
