Answer 1

-3/7= -15/35= -30/70.

-2/5= -14/35= -28/70.

So ans:- -29/30.

Similarly you can find infinite rational number between 2 rational numbers.

Answer 2

Answer:

The rational numbers that lies between $-\frac{3}{7}$ and $-\frac{2}{5}$ are  $-\frac{141}{350}, -\frac{142}{350}, -\frac{143}{350}, -\frac{144}{350}, -\frac{145}{350}, -\frac{146}{350}, -\frac{147}{350}, -\frac{148}{350}$ and $-\frac{149}{350}$.

Step-by-step explanation:

$-\frac{3}{7} = -\frac{3 \times 5}{7\times 5} = -\frac{15}{35} = -\frac{150}{350}$

$-\frac{2}{5} = -\frac{2 \times 7}{5\times 7} = -\frac{140}{350}$

The rational numbers that lies between $-\frac{3}{7}$ and $-\frac{2}{5}$ are  $-\frac{141}{350}, -\frac{142}{350}, -\frac{143}{350}, -\frac{144}{350}, -\frac{145}{350}, -\frac{146}{350}, -\frac{147}{350}, -\frac{148}{350}$ and $-\frac{149}{350}$.
