Kua tāruatia ki te papatopenga
\frac{7}{8}b=1-\frac{1}{4}
Whakaarohia te whārite tuatahi. Tangohia te \frac{1}{4} mai i ngā taha e rua.
\frac{7}{8}b=\frac{3}{4}
Tangohia te \frac{1}{4} i te 1, ka \frac{3}{4}.
b=\frac{3}{4}\times \frac{8}{7}
Me whakarea ngā taha e rua ki te \frac{8}{7}, te tau utu o \frac{7}{8}.
b=\frac{6}{7}
Whakareatia te \frac{3}{4} ki te \frac{8}{7}, ka \frac{6}{7}.
b=\frac{6}{7} c=2 d=2
Kua oti te pūnaha te whakatau.
