Question

three rational no between 4/5 and -2/3

Answer 1

1/2(4/5+(-2/3) )
1/2(12+(-10)/15
1/2(12-10/15)
1/2÷2/15
1/2×15/2
=15/4 is first rational no.
Now,2nd rational no.
1/2(4/5+15/4)
1/2(16+60/20)
1/2÷76/20
1/2×20/76
=10/76 is 2nd rational no.
Now,3rd rational no.
1/2(15/4+(-2/3) )
1/2(45+(-8)/12 )
1/2(45-8/12)
1/2÷37/12
1/2×12/37
=6/37 is the third rational no.
