Question

$$3\times\frac{4}{-7}+15$$

Evaluate

$\frac{93}{7}\approx 13.285714286$

Solution Steps

Fraction $\frac{4}{-7}$ can be rewritten as $-\frac{4}{7}$ by extracting the negative sign.

$$3\left(-\frac{4}{7}\right)+15$$

Express $3\left(-\frac{4}{7}\right)$ as a single fraction.

$$\frac{3\left(-4\right)}{7}+15$$

Multiply $3$ and $-4$ to get $-12$.

$$\frac{-12}{7}+15$$

Fraction $\frac{-12}{7}$ can be rewritten as $-\frac{12}{7}$ by extracting the negative sign.

$$-\frac{12}{7}+15$$

Convert $15$ to fraction $\frac{105}{7}$.

$$-\frac{12}{7}+\frac{105}{7}$$

Since $-\frac{12}{7}$ and $\frac{105}{7}$ have the same denominator, add them by adding their numerators.

$$\frac{-12+105}{7}$$

Add $-12$ and $105$ to get $93$.

$$\frac{93}{7}$$
