7.Find five rational numbers between 3/5 and 4/5.
8.Find ten rational numbers between -2/5 and 1/7​

Answer 1

Step-by-step explanation:

( 1 ).As we have to find 5 rational no multiplying the numbers by 6/6

3/5=3/5×6/6 = 18/30

4/5=4/5×6/6 = 24/30

Therefore five rational no between 3/5 and 4/5 are

19/30, 20/30, 21/30, 22/30, 23/30

( 2 ). the rational numbers -2/5 and 1/7

by taking LCM 5 and 7 is 35

so

- 2/5 = (-2×7) (5×7)= -14/35

1/7 = ( 1× 5) ( 7×5)= 5/35

10 numbers between are -14/35 and 5/35

-13/35 'to 4/35

hence the ten rational no between -2/5 and 1/7

-6/35 , -5/35 , -4/35 ,-3/35 ,-2/35 ,-1/35, 1/35, 2/35, 3/35 , 4/35
