Simplify: $$\left(2\frac{1}{2} + 3.6\right) \div 0.75 + \left(1.25 \times \frac{4}{5}\right)$$​​

Correct option is A

Given :

​$$\left(2\frac{1}{2} + 3.6\right) \div 0.75 + \left(1.25 \times \frac{4}{5}\right)$$​​
Solution:

$$(2.5 + 3.6)\div 0.75 + (1.25 \times 0.8) \\ \ \\= 6.1 \div 0.75 + 1\\ \ \\= \frac{61}{10}\times\frac{4}{3} + 1\\ \ \\= \frac{244}{30} + 1\\ \ \\= \frac{122}{15} + \frac{15}{15}\\ \ \\= \frac{137}{15}$$​​
