Answer:

1/20 , -9/40 , -7/80 and 13/40

step by step explanation:

-1/2 and 3/5

1/2 × (-1/2 + 3/5)

= 1/2 × {(-5+6) / 10}

= 1/2 × 1/10

= 1/20

-1/2 < 1/20 < 3/5

1/2 × (-1/2 + 1/20)

= 1/2 × {(-10+1) / 20}

= 1/2 ×-9/20

= -9/40

-1/2 < -9/40 < 1/20 < 3/5

1/2 × (-9/40 + 1/20)

= 1/2 × {(-9+2)/ 40}

= 1/2 × -7/40

= -7/80

-1/2 < -9/40 < -7/80 < 1/20 < 3/5

1/2 × (1/20+3/5)

= 1/2× {(1+2)/20}

= 1/2×13=20

= 13/40

-1/2 < -9/40 < -7/80 < 1/20 < 13/49 < 3/5

so, four rational numbers between -1/2 and 3/5 are

-9/40 , -7/80 ,1/20 and 13/40
