Answer 1

Answer:

$\frac{51}{10}$

Step-by-step explanation:

$7 \frac{4}{5} - 2 \frac{7}{10}$

$\frac{5 \times 7 + 4}{5} - \frac{10 \times 2 + 7}{10}$

$\frac{39}{5} - \frac{27}{10}$

$lcm \: of \: 5\:10 \: is \: 10$

$\frac{39}{5} \times \frac{2}{2} - \frac{27}{10} \times \frac{1}{1}$

$\frac{78}{10} - \frac{27}{10}$

$\frac{78 - 27}{10}$

$\frac{51}{10}$
