Question

2/9,5/12,-7/15,8/-18​

Answer 1

Answer :

To do

• we have to write the following rational numbers in descending order.

For this,

• We have to firstly make the denominators same.

= $\dfrac{2}{9}$ ; $\dfrac{5}{12}$ ; $\dfrac{-7}{15}$ ; $\dfrac{-8}{18}$

= $\dfrac{40}{180}$ ; $\dfrac{75}{180}$ ; $\dfrac{-84}{180}$ ; $\dfrac{-80}{180}$

Now,

• Arrange them into descending order , that is

= $\dfrac{-84}{180}$ < $\dfrac{-80}{180}$ < $\dfrac{40}{180}$ < $\dfrac{75}{180}$
