Solve 31/4-4*(-0,5)^2

$$3 \frac { 1 } { 4 } - 4 \cdot ( - 0,5 ) ^ { 2 }$$

Evaluate

$$2,25$$

Solution Steps

Multiply 3 and 4 to get 12.

$$\frac{12+1}{4}-4\left(-0,5\right)^{2}$$

Add 12 and 1 to get 13.

$$\frac{13}{4}-4\left(-0,5\right)^{2}$$

Calculate -0,5 to the power of 2 and get 0,25.

$$\frac{13}{4}-4\times 0,25$$

Multiply 4 and 0,25 to get 1.

$$\frac{13}{4}-1$$

Convert 1 to fraction \frac{4}{4}.

$$\frac{13}{4}-\frac{4}{4}$$

Since \frac{13}{4} and \frac{4}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{13-4}{4}$$

Subtract 4 from 13 to get 9.

$$\frac{9}{4}$$

Factor

$$\frac{3 ^ {2}}{2 ^ {2}} = 2\frac{1}{4} = 2.25$$
