Question

$$\frac{ -11 }{ 15 } + \frac{ 21 }{ 25 }$$

Evaluate

$\frac{8}{75}\approx 0.106666667$

Solution Steps

Fraction $\frac{-11}{15}$ can be rewritten as $-\frac{11}{15}$ by extracting the negative sign.

$$-\frac{11}{15}+\frac{21}{25}$$

Least common multiple of $15$ and $25$ is $75$. Convert $-\frac{11}{15}$ and $\frac{21}{25}$ to fractions with denominator $75$.

$$-\frac{55}{75}+\frac{63}{75}$$

Since $-\frac{55}{75}$ and $\frac{63}{75}$ have the same denominator, add them by adding their numerators.

$$\frac{-55+63}{75}$$

Add $-55$ and $63$ to get $8$.

$$\frac{8}{75}$$

Factor

$\frac{2 ^ {3}}{3 \cdot 5 ^ {2}} = 0.10666666666666667$
