Question

insert 10 rational numbers between -1 and minus 1 by 3

Answer 1

-1 = -1/1 = -3/3
-1/3 = -1/3 =-1/ 3( hahaha) ( what we need is to make the denominators equal)
Now multiplying both the numerator and the denomenator of the both by 100
We get
-3 *100/ 3*100 = -300/300 (-300/300 = -1/1 =-1)
-1* 100/ 3*100 =-100/300(....................................)
we have got the denominators equal..now we can say that
-200/300(= -2/3), -199/300, -198/300, -197/300, -195/300, .......................

N.B. U can take any no. as numerator BUT the no. should be between -300 and -100

Hope it helped
