$$- \frac{ 4 }{ 5 } - \frac{ 3 }{ 7 }$$

$-\frac{43}{35}\approx -1.228571429$

Least common multiple of $5$ and $7$ is $35$. Convert $-\frac{4}{5}$ and $\frac{3}{7}$ to fractions with denominator $35$.

$$-\frac{28}{35}-\frac{15}{35}$$

Since $-\frac{28}{35}$ and $\frac{15}{35}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-28-15}{35}$$

Subtract $15$ from $-28$ to get $-43$.

$$-\frac{43}{35}$$

$-\frac{43}{35} = -1\frac{8}{35} = -1.2285714285714286$
