0.27 = 27/100
0.30 = 30/100 = 3/10
!/2( 27/100 + 30/100)
1/2 ( 57/100)
57/200.... (1)

1/2( 57/200 + 30/100)
1/2 ( 117/200)
117/400....... (2)

in this manner we can find three more rational nos..... best of luck!

Its  easy one method is you take both no. and then divide them by 2 again what you obtain add it one of the numbers and divide by 2 or take both the numbers in this case 27/100 and 30/100 you need to make the denominators equal in this case they are equal (you are lucky)  now since we only get 28/100 and 29/100  we would need to multiply both by 2 and then write no . in between them that are not equal to numbers you already wrote.
