Answer 2

Answer:

-1/4 < 5/21 < 2/7 < 1/3

Step-by-step explanation:

In -1/4 , 1/3 , 2/7 and 5/21

firstly we can calculate L.C.M of denominators

L.C.M of 4 , 21 , 7 , 3 = 84

then we can write all no. in terms of 84 denominator

$- \frac{1}{4} \times \frac{21}{21} = - \frac{21}{84} \\ \\ \frac{1}{3} \times \frac{28}{28} = \frac{28}{84} \\ \\ \frac{2}{7} \times \frac{12}{12} = \frac{24}{84} \\ \\ \frac{5}{21} \times \frac{4}{4} = \frac{20}{84}$

-21/84 , 28/84 , 24/84 , 20/84

ascending order

= -21/84 < 20/84 < 24/84 < 28/84

= -1/4 < 5/21 < 2/7 < 1/3
