x\left(\frac{12}{20}+\frac{5}{20}\right)-\frac{1}{4}=\frac{11}{160}
Ko te maha noa iti rawa atu o 5 me 4 ko 20. Me tahuri \frac{3}{5} me \frac{1}{4} ki te hautau me te tautūnga 20.
x\times \frac{12+5}{20}-\frac{1}{4}=\frac{11}{160}
Tā te mea he rite te tauraro o \frac{12}{20} me \frac{5}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
x\times \frac{17}{20}-\frac{1}{4}=\frac{11}{160}
Tāpirihia te 12 ki te 5, ka 17.
x\times \frac{17}{20}=\frac{11}{160}+\frac{1}{4}
Me tāpiri te \frac{1}{4} ki ngā taha e rua.
x\times \frac{17}{20}=\frac{11}{160}+\frac{40}{160}
Ko te maha noa iti rawa atu o 160 me 4 ko 160. Me tahuri \frac{11}{160} me \frac{1}{4} ki te hautau me te tautūnga 160.
x\times \frac{17}{20}=\frac{11+40}{160}
Tā te mea he rite te tauraro o \frac{11}{160} me \frac{40}{160}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
x\times \frac{17}{20}=\frac{51}{160}
Tāpirihia te 11 ki te 40, ka 51.
x=\frac{51}{160}\times \frac{20}{17}
Me whakarea ngā taha e rua ki te \frac{20}{17}, te tau utu o \frac{17}{20}.
x=\frac{51\times 20}{160\times 17}
Me whakarea te \frac{51}{160} ki te \frac{20}{17} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{1020}{2720}
Mahia ngā whakarea i roto i te hautanga \frac{51\times 20}{160\times 17}.
x=\frac{3}{8}
Whakahekea te hautanga \frac{1020}{2720} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 340.
