Solve -3/4--4/5

$$\frac{ -3 }{ 4 } - \frac{ -4 }{ 5 }$$

Evaluate

$$\frac{1}{20}=0.05$$

Solution Steps

Fraction \frac{-3}{4} can be rewritten as -\frac{3}{4} by extracting the negative sign.

$$-\frac{3}{4}-\frac{-4}{5}$$

Fraction \frac{-4}{5} can be rewritten as -\frac{4}{5} by extracting the negative sign.

$$-\frac{3}{4}-\left(-\frac{4}{5}\right)$$

The opposite of -\frac{4}{5} is \frac{4}{5}.

$$-\frac{3}{4}+\frac{4}{5}$$

Least common multiple of 4 and 5 is 20. Convert -\frac{3}{4} and \frac{4}{5} to fractions with denominator 20.

$$-\frac{15}{20}+\frac{16}{20}$$

Since -\frac{15}{20} and \frac{16}{20} have the same denominator, add them by adding their numerators.

$$\frac{-15+16}{20}$$

Add -15 and 16 to get 1.

$$\frac{1}{20}$$

Factor

$$\frac{1}{2 ^ {2} \cdot 5} = 0.05$$
