Solve (-12)-3/8div(-3)-2*(-5)

$$(-12)- \frac{ 3 }{ 8 } \div (-3)-2 \times (-5)$$

Evaluate

$$-\frac{15}{8}=-1.875$$

Solution Steps

Express \frac{\frac{3}{8}}{-3} as a single fraction.

$$-12-\frac{3}{8\left(-3\right)}-2\left(-5\right)$$

Multiply 8 and -3 to get -24.

$$-12-\frac{3}{-24}-2\left(-5\right)$$

Reduce the fraction \frac{3}{-24} to lowest terms by extracting and canceling out 3.

$$-12-\left(-\frac{1}{8}\right)-2\left(-5\right)$$

The opposite of -\frac{1}{8} is \frac{1}{8}.

$$-12+\frac{1}{8}-2\left(-5\right)$$

Convert -12 to fraction -\frac{96}{8}.

$$-\frac{96}{8}+\frac{1}{8}-2\left(-5\right)$$

Since -\frac{96}{8} and \frac{1}{8} have the same denominator, add them by adding their numerators.

$$\frac{-96+1}{8}-2\left(-5\right)$$

Add -96 and 1 to get -95.

$$-\frac{95}{8}-2\left(-5\right)$$

Multiply 2 and -5 to get -10.

$$-\frac{95}{8}-\left(-10\right)$$

The opposite of -10 is 10.

$$-\frac{95}{8}+10$$

Convert 10 to fraction \frac{80}{8}.

$$-\frac{95}{8}+\frac{80}{8}$$

Since -\frac{95}{8} and \frac{80}{8} have the same denominator, add them by adding their numerators.

$$\frac{-95+80}{8}$$

Add -95 and 80 to get -15.

$$-\frac{15}{8}$$

Factor

$$-\frac{15}{8} = -1\frac{7}{8} = -1.875$$
