Question

Are they represent equal rational numbers? Why or why not?
(i) (-16)/( 24) and 20/(-16) (ii) 21/( -32) and 70/(-105) and (-280)/( 420)

Answer 1

Answer:

minus 16 upon 24 equals to minus 2 upon 3 and 20 upon 16 will be 5 upon - 4 no they are not same because if we write them in simplest form they are not same second part 21 upon -32 will remain same and 70 upon - 105will not be saved because 70 is not equal to 21 because they are not factors or multiples so it is clear that the vote do not represent equal rational numbers and at last - 280 upon 420 will be equal to minus 2 upon 3 that's also not same with any of the option yes yes as you can see that -16 upon 24 is equals to minus 2 80 upon 4 20 only these are same else are not same
