$$\frac{ 7 }{ 10 } - \frac{ 4 }{ 15 }$$

$\frac{13}{30}\approx 0.433333333$

Least common multiple of $10$ and $15$ is $30$. Convert $\frac{7}{10}$ and $\frac{4}{15}$ to fractions with denominator $30$.

$$\frac{21}{30}-\frac{8}{30}$$

Since $\frac{21}{30}$ and $\frac{8}{30}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{21-8}{30}$$

Subtract $8$ from $21$ to get $13$.

$$\frac{13}{30}$$

$\frac{13}{2 \cdot 3 \cdot 5} = 0.43333333333333335$
