Now you need 10 rational numbers. So multiply denominator and numerator of both numbers with 10 for easy.

120/200 and 150/200

Now between these numbers

121/200, 122/200, 123/200,  124/200, 125/200, 126/200, 127/200, 128/200, 129/200, 130/200

You will get more number but take only 10 rational numbers
