Question

$$4/2-6/7-9/5=$$

Evaluate

$-\frac{23}{35}\approx -0.657142857$

Solution Steps

Divide $4$ by $2$ to get $2$.

$$2-\frac{6}{7}-\frac{9}{5}$$

Convert $2$ to fraction $\frac{14}{7}$.

$$\frac{14}{7}-\frac{6}{7}-\frac{9}{5}$$

Since $\frac{14}{7}$ and $\frac{6}{7}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{14-6}{7}-\frac{9}{5}$$

Subtract $6$ from $14$ to get $8$.

$$\frac{8}{7}-\frac{9}{5}$$

Least common multiple of $7$ and $5$ is $35$. Convert $\frac{8}{7}$ and $\frac{9}{5}$ to fractions with denominator $35$.

$$\frac{40}{35}-\frac{63}{35}$$

Since $\frac{40}{35}$ and $\frac{63}{35}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{40-63}{35}$$

Subtract $63$ from $40$ to get $-23$.

$$-\frac{23}{35}$$
