30.8=\frac{27}{28}
Tāpirihia te 30 ki te 0.8, ka 30.8.
\frac{154}{5}=\frac{27}{28}
Me tahuri ki tau ā-ira 30.8 ki te hautau \frac{308}{10}. Whakahekea te hautanga \frac{308}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{4312}{140}=\frac{135}{140}
Ko te maha noa iti rawa atu o 5 me 28 ko 140. Me tahuri \frac{154}{5} me \frac{27}{28} ki te hautau me te tautūnga 140.
\text{false}
Whakatauritea te \frac{4312}{140} me te \frac{135}{140}.
