Question

$$\frac{ 3 }{ 5 } + \frac{ 7 }{ 5 } - \frac{ 9 }{ 5 } - \frac{ 4 }{ 5 }$$

Evaluate

$-\frac{3}{5}=-0.6$

Solution Steps

Since $\frac{3}{5}$ and $\frac{7}{5}$ have the same denominator, add them by adding their numerators.

$$\frac{3+7}{5}-\frac{9}{5}-\frac{4}{5}$$

Add $3$ and $7$ to get $10$.

$$\frac{10}{5}-\frac{9}{5}-\frac{4}{5}$$

Since $\frac{10}{5}$ and $\frac{9}{5}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{10-9}{5}-\frac{4}{5}$$

Subtract $9$ from $10$ to get $1$.

$$\frac{1}{5}-\frac{4}{5}$$

Since $\frac{1}{5}$ and $\frac{4}{5}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{1-4}{5}$$

Subtract $4$ from $1$ to get $-3$.

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

Factor

$-\frac{3}{5} = -0.6$
