Quin made three and four sevenths jugs of sweet tea. She sold two and one third jugs at her sweet tea stand. How much sweet tea

Lera25 [3.4K]

Answer: $\frac{23}{21}\ \text{Jugs of tea}$

Step-by-step explanation:

Given

Quin made three and four seventh jugs of sweet tea i.e. $3 \frac{4}{7}=\frac{3\times 7+4}{7}=\frac{25}{7}\ jugs$

She sold two and one-third jugs i.e. $2 \frac{1}{3}=\frac{2\times 3+1}{3}=\frac{7}{3}\ jugs$

Remaining tea= $\frac{25}{7}-\frac{7}{3}=\frac{24\times 3-7\times 7}{21}\\$

$=\frac{72-49}{21}=\frac{23}{21}\ \text{Jugs of tea}$
