Answer:[tex]\frac{23}{21}\ \text{Jugs of tea}[/tex]
Step-by-step explanation:
Given
Quin made three and four seventh jugs of sweet tea i.e. [tex]3 \frac{4}{7}=\frac{3\times 7+4}{7}=\frac{25}{7}\ jugs[/tex]
She sold two and one-third jugs i.e. [tex]2 \frac{1}{3}=\frac{2\times 3+1}{3}=\frac{7}{3}\ jugs[/tex]
Remaining tea= [tex]\frac{25}{7}-\frac{7}{3}=\frac{24\times 3-7\times 7}{21}\\[/tex]
[tex]=\frac{72-49}{21}=\frac{23}{21}\ \text{Jugs of tea}[/tex]
