Solve 7*5-2div4*5+5+5+5-22

$$7 \times 5-2 \div 4 \times 5+5+5+5-22$$

Evaluate

$$\frac{51}{2}=25.5$$

Solution Steps

Multiply 7 and 5 to get 35.

$$35-\frac{2}{4}\times 5+5+5+5-22$$

Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.

$$35-\frac{1}{2}\times 5+5+5+5-22$$

Multiply \frac{1}{2} and 5 to get \frac{5}{2}.

$$35-\frac{5}{2}+5+5+5-22$$

Convert 35 to fraction \frac{70}{2}.

$$\frac{70}{2}-\frac{5}{2}+5+5+5-22$$

Since \frac{70}{2} and \frac{5}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{70-5}{2}+5+5+5-22$$

Subtract 5 from 70 to get 65.

$$\frac{65}{2}+5+5+5-22$$

Convert 5 to fraction \frac{10}{2}.

$$\frac{65}{2}+\frac{10}{2}+5+5-22$$

Since \frac{65}{2} and \frac{10}{2} have the same denominator, add them by adding their numerators.

$$\frac{65+10}{2}+5+5-22$$

Add 65 and 10 to get 75.

$$\frac{75}{2}+5+5-22$$

Convert 5 to fraction \frac{10}{2}.

$$\frac{75}{2}+\frac{10}{2}+5-22$$

Since \frac{75}{2} and \frac{10}{2} have the same denominator, add them by adding their numerators.

$$\frac{75+10}{2}+5-22$$

Add 75 and 10 to get 85.

$$\frac{85}{2}+5-22$$

Convert 5 to fraction \frac{10}{2}.

$$\frac{85}{2}+\frac{10}{2}-22$$

Since \frac{85}{2} and \frac{10}{2} have the same denominator, add them by adding their numerators.

$$\frac{85+10}{2}-22$$

Add 85 and 10 to get 95.

$$\frac{95}{2}-22$$

Convert 22 to fraction \frac{44}{2}.

$$\frac{95}{2}-\frac{44}{2}$$

Since \frac{95}{2} and \frac{44}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{95-44}{2}$$

Subtract 44 from 95 to get 51.

$$\frac{51}{2}$$

Factor

$$\frac{3 \cdot 17}{2} = 25\frac{1}{2} = 25.5$$
