Solve (-1/8)*(2/3)*2^-3+(1/4)=

$$( - \frac { 1 } { 8 } ) \cdot ( \frac { 2 } { 3 } ) \cdot 2 ^ { - 3 } + ( \frac { 1 } { 4 } ) =$$

Evaluate

$$\frac{23}{96}\approx 0.239583333$$

Solution Steps

Multiply -\frac{1}{8} and \frac{2}{3} to get -\frac{1}{12}.

$$-\frac{1}{12}\times 2^{-3}+\frac{1}{4}$$

Calculate 2 to the power of -3 and get \frac{1}{8}.

$$-\frac{1}{12}\times \frac{1}{8}+\frac{1}{4}$$

Multiply -\frac{1}{12} and \frac{1}{8} to get -\frac{1}{96}.

$$-\frac{1}{96}+\frac{1}{4}$$

Add -\frac{1}{96} and \frac{1}{4} to get \frac{23}{96}.

$$\frac{23}{96}$$

Factor

$$\frac{23}{2 ^ {5} \cdot 3} = 0.23958333333333334$$
