Question

$$(3/10-10/10) \times (2/4+1/2)$$

Evaluate

$-\frac{7}{10}=-0.7$

Solution Steps

Since $\frac{3}{10}$ and $\frac{10}{10}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{3-10}{10}\left(\frac{2}{4}+\frac{1}{2}\right)$$

Subtract $10$ from $3$ to get $-7$.

$$-\frac{7}{10}\left(\frac{2}{4}+\frac{1}{2}\right)$$

Reduce the fraction $\frac{2}{4}$ to lowest terms by extracting and canceling out $2$.

$$-\frac{7}{10}\left(\frac{1}{2}+\frac{1}{2}\right)$$

Since $\frac{1}{2}$ and $\frac{1}{2}$ have the same denominator, add them by adding their numerators.

$$-\frac{7}{10}\times \frac{1+1}{2}$$

Add $1$ and $1$ to get $2$.

$$-\frac{7}{10}\times \frac{2}{2}$$

Divide $2$ by $2$ to get $1$.

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

Factor

$-\frac{7}{10} = -0.7$
