Solve 81/2+(-1/4)-5-5*0,25

$$8 \frac { 1 } { 2 } + ( - \frac { 1 } { 4 } ) - 5 - 5 \times 0,25$$

Evaluate

$$2$$

Solution Steps

Multiply 8 and 2 to get 16.

$$\frac{16+1}{2}-\frac{1}{4}-5-5\times 0,25$$

Add 16 and 1 to get 17.

$$\frac{17}{2}-\frac{1}{4}-5-5\times 0,25$$

Least common multiple of 2 and 4 is 4. Convert \frac{17}{2} and \frac{1}{4} to fractions with denominator 4.

$$\frac{34}{4}-\frac{1}{4}-5-5\times 0,25$$

Since \frac{34}{4} and \frac{1}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{34-1}{4}-5-5\times 0,25$$

Subtract 1 from 34 to get 33.

$$\frac{33}{4}-5-5\times 0,25$$

Convert 5 to fraction \frac{20}{4}.

$$\frac{33}{4}-\frac{20}{4}-5\times 0,25$$

Since \frac{33}{4} and \frac{20}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{33-20}{4}-5\times 0,25$$

Subtract 20 from 33 to get 13.

$$\frac{13}{4}-5\times 0,25$$

Multiply 5 and 0,25 to get 1,25.

$$\frac{13}{4}-1,25$$

Convert decimal number 1,25 to fraction \frac{125}{100}. Reduce the fraction \frac{125}{100} to lowest terms by extracting and canceling out 25.

$$\frac{13}{4}-\frac{5}{4}$$

Since \frac{13}{4} and \frac{5}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{13-5}{4}$$

Subtract 5 from 13 to get 8.

$$\frac{8}{4}$$

Divide 8 by 4 to get 2.

$$2$$

Factor

$$2$$
