If $$6\frac{1}{2} ×2 \frac{4}{5} ÷ x = \frac{7}{10},$$ then find x:​

Correct option is A

Given: 

​$$6\frac{1}{2} ×2 \frac{4}{5} ÷ x = \frac{7}{10},$$ 

Solution:

$$6\frac{1}{2} ×2 \frac{4}{5} ÷ x = \frac{7}{10}\\ \ \\ \frac{13}{2} × \frac{14}{5}×\frac{1}{x} = \frac{7}{10} \\ \ \\\frac{13×7}{5×x}= \frac{7}{10}\\ \ \bf x= 26$$​​
