Solve [-1+1/1.5-1]

$$[ - 1 + \frac { 1 } { 1.5 } - 1 ]$$

Evaluate

$$-\frac{4}{3}\approx -1.333333333$$

Solution Steps

Expand \frac{1}{1.5} by multiplying both numerator and the denominator by 10.

$$-1+\frac{10}{15}-1$$

Reduce the fraction \frac{10}{15} to lowest terms by extracting and canceling out 5.

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

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

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

Since -\frac{3}{3} and \frac{2}{3} have the same denominator, add them by adding their numerators.

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

Add -3 and 2 to get -1.

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

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

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

Since -\frac{1}{3} and \frac{3}{3} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 3 from -1 to get -4.

$$-\frac{4}{3}$$

Factor

$$-\frac{4}{3} = -1\frac{1}{3} = -1.3333333333333333$$
