2)Multiply the negative of 2/3 by the inverse 9/7​

Answer 1

Answer:

1/3 , 4/5

LCM of 3 and 5 = 15

1×5/3×5 , 4×3/5×3

5/15 , 12/15

Three rational numbers between 1/3 and 4/5 = 6/12 , 7/12 , 8/12

In case of additive inverse

-2/3 × (-9/7)

= 6/7

In case of multiplicative inverse

-2/3 × (7/9)

= -14/27
