\frac{x}{0.24}=\frac{105}{84}
Whakarohaina te \frac{1.05}{0.84} mā te whakarea i te taurunga me te tauraro ki te 100.
\frac{x}{0.24}=\frac{5}{4}
Whakahekea te hautanga \frac{105}{84} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 21.
x=\frac{5}{4}\times 0.24
Me whakarea ngā taha e rua ki te 0.24.
x=\frac{5}{4}\times \frac{6}{25}
Me tahuri ki tau ā-ira 0.24 ki te hautau \frac{24}{100}. Whakahekea te hautanga \frac{24}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
x=\frac{5\times 6}{4\times 25}
Me whakarea te \frac{5}{4} ki te \frac{6}{25} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{30}{100}
Mahia ngā whakarea i roto i te hautanga \frac{5\times 6}{4\times 25}.
x=\frac{3}{10}
Whakahekea te hautanga \frac{30}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
