Solve -1/2+3/5--0*4

$$- \frac{ 1 }{ 2 } + \frac{ 3 }{ 5 } --0 \cdot 4$$

Evaluate

$$\frac{1}{10}=0.1$$

Solution Steps

Least common multiple of 2 and 5 is 10. Convert -\frac{1}{2} and \frac{3}{5} to fractions with denominator 10.

$$-\frac{5}{10}+\frac{6}{10}-0\times 4$$

Since -\frac{5}{10} and \frac{6}{10} have the same denominator, add them by adding their numerators.

$$\frac{-5+6}{10}-0\times 4$$

Add -5 and 6 to get 1.

$$\frac{1}{10}-0\times 4$$

Multiply 0 and 4 to get 0.

$$\frac{1}{10}-0$$

Subtract 0 from \frac{1}{10} to get \frac{1}{10}.

$$\frac{1}{10}$$

Factor

$$\frac{1}{2 \cdot 5} = 0.1$$
