Solve -1/3--2+-1

$$\frac{ -1 }{ 3 } --2+-1$$

Evaluate

$$\frac{2}{3}\approx 0.666666667$$

Solution Steps

Fraction \frac{-1}{3} can be rewritten as -\frac{1}{3} by extracting the negative sign.

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

The opposite of -2 is 2.

$$-\frac{1}{3}+2-1$$

Convert 2 to fraction \frac{6}{3}.

$$-\frac{1}{3}+\frac{6}{3}-1$$

Since -\frac{1}{3} and \frac{6}{3} have the same denominator, add them by adding their numerators.

$$\frac{-1+6}{3}-1$$

Add -1 and 6 to get 5.

$$\frac{5}{3}-1$$

Convert 1 to fraction \frac{3}{3}.

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

Since \frac{5}{3} and \frac{3}{3} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 3 from 5 to get 2.

$$\frac{2}{3}$$

Factor

$$\frac{2}{3} = 0.6666666666666666$$
