Solve 9/4-4(-1/2)(-1)=

$$\frac { 9 } { 4 } - 4 ( - \frac { 1 } { 2 } ) ( - 1 ) =$$

Evaluate

$$\frac{1}{4}=0.25$$

Solution Steps

Express 4\left(-\frac{1}{2}\right) as a single fraction.

$$\frac{9}{4}-\frac{4\left(-1\right)}{2}\left(-1\right)$$

Multiply 4 and -1 to get -4.

$$\frac{9}{4}-\frac{-4}{2}\left(-1\right)$$

Divide -4 by 2 to get -2.

$$\frac{9}{4}-\left(-2\left(-1\right)\right)$$

Multiply -2 and -1 to get 2.

$$\frac{9}{4}-2$$

Convert 2 to fraction \frac{8}{4}.

$$\frac{9}{4}-\frac{8}{4}$$

Since \frac{9}{4} and \frac{8}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{9-8}{4}$$

Subtract 8 from 9 to get 1.

$$\frac{1}{4}$$

Factor

$$\frac{1}{2 ^ {2}} = 0.25$$
