Answer 2

Answer:

Ascending order -

=$\frac{1}{5} . \frac{3}{7} . \frac{13}{28} . \frac{7}{10}$

ㅤ

Descending Order-

= $\frac{7}{10} . \frac{13}{28} . \frac{3}{7} . \frac{1}{5}$

Step-by-step explanation:

$\frac{1}{5} . \frac{3}{7} . \frac{7}{10} . \frac{13}{28} \\ \\ = lcm = 5 \times 7 \times 4 = 35 \times 4 = 140 \\ \\ = \frac{1}{5} \times \frac{28}{28} = \frac{28}{140} \\ \\ = \frac{3}{7} \times \frac{20}{20} = \frac{60}{140} \\ \\ = \frac{7}{10} \times \frac{14}{14} = \frac{98}{140} \\ \\ = \frac{13}{28} \times \frac{5}{5} = \frac{65}{140}$
