Answer 2

Answer:

$- \frac{2}{3 } < \frac{1 }{2} < \frac{4}{7} < \frac{4}{5}$

Step-by-step explanation:

Take The LCM of Denominators

3,2,7,5 = 210

$\frac{4 \times 42}{5 \times 42} . \frac{ - 2 \times 70}{3 \times 70}. \frac{1 \times 105}{2 \times 105} . \frac{4 \times 30}{7 \times 30}$

$\frac{168}{210} . \frac{ - 140}{210} . \frac{105}{210} . \frac{120}{210}$

$\frac{ - 140}{210 } < \frac{105}{210} < \frac{120}{210} < \frac{168}{210}$

$= \frac{ - 2}{3} < \frac{1}{2} < \frac{4}{7} < \frac{4}{5}$
