Question

Which rational number is greater than -31/3 but less than-4/5 -0.4,-0.19,-9/7,-22/5?

Answer 1

One way to do this is to convert the fractions to decimal. So:-
-31/3  = -10.33....
4/5 = -0.8 

-9/7 = -1.285714286.....
-22/5 = -4.4

The answer is -4.4 ( -22/5)   ( Not  -9/7 because this is irrational).
