Solve -3-(-2,2)-(-1/15)

$$- 3 - ( - 2,2 ) - ( - \frac { 1 } { 15 } )$$

Evaluate

$$-\frac{11}{15}\approx -0,733333333$$

Solution Steps

The opposite of -2,2 is 2,2.

$$-3+2,2-\left(-\frac{1}{15}\right)$$

Add -3 and 2,2 to get -0,8.

$$-0,8-\left(-\frac{1}{15}\right)$$

The opposite of -\frac{1}{15} is \frac{1}{15}.

$$-0,8+\frac{1}{15}$$

Convert decimal number -0,8 to fraction -\frac{8}{10}. Reduce the fraction -\frac{8}{10} to lowest terms by extracting and canceling out 2.

$$-\frac{4}{5}+\frac{1}{15}$$

Least common multiple of 5 and 15 is 15. Convert -\frac{4}{5} and \frac{1}{15} to fractions with denominator 15.

$$-\frac{12}{15}+\frac{1}{15}$$

Since -\frac{12}{15} and \frac{1}{15} have the same denominator, add them by adding their numerators.

$$\frac{-12+1}{15}$$

Add -12 and 1 to get -11.

$$-\frac{11}{15}$$

Factor

$$-\frac{11}{15} = -0.7333333333333333$$
