140.28=\frac{20}{100}
Whakareatia te 7 ki te 20.04, ka 140.28.
140.28=\frac{1}{5}
Whakahekea te hautanga \frac{20}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
\frac{3507}{25}=\frac{1}{5}
Me tahuri ki tau ā-ira 140.28 ki te hautau \frac{14028}{100}. Whakahekea te hautanga \frac{14028}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
\frac{3507}{25}=\frac{5}{25}
Ko te maha noa iti rawa atu o 25 me 5 ko 25. Me tahuri \frac{3507}{25} me \frac{1}{5} ki te hautau me te tautūnga 25.
\text{false}
Whakatauritea te \frac{3507}{25} me te \frac{5}{25}.
