Answer :
All you have to do is add the two rational numbers and divide it by 2.
Then you get an answer.
Again add the answer and the second number and divide by 2.
Continue this until you get five answer.
So the answers are:
0.285
0.2925
0.29625
0.298125
0.2990625
Then you get an answer.
Again add the answer and the second number and divide by 2.
Continue this until you get five answer.
So the answers are:
0.285
0.2925
0.29625
0.298125
0.2990625
Consider 0.27 = 27/100 = 54/200
Similarly 0.30 = 30/100 = 60/200
Hence the numbers between 0.27 and 0.30 are 55/200, 56/200, 57/200 up to 59/200.
