Solve 20div2-4div8+240+500

$$20 \div 2 - 4 \div 8 + 240 + 500$$

Evaluate

$$\frac{1499}{2}=749.5$$

Solution Steps

Divide 20 by 2 to get 10.

$$10-\frac{4}{8}+240+500$$

Reduce the fraction \frac{4}{8} to lowest terms by extracting and canceling out 4.

$$10-\frac{1}{2}+240+500$$

Convert 10 to fraction \frac{20}{2}.

$$\frac{20}{2}-\frac{1}{2}+240+500$$

Since \frac{20}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{20-1}{2}+240+500$$

Subtract 1 from 20 to get 19.

$$\frac{19}{2}+240+500$$

Convert 240 to fraction \frac{480}{2}.

$$\frac{19}{2}+\frac{480}{2}+500$$

Since \frac{19}{2} and \frac{480}{2} have the same denominator, add them by adding their numerators.

$$\frac{19+480}{2}+500$$

Add 19 and 480 to get 499.

$$\frac{499}{2}+500$$

Convert 500 to fraction \frac{1000}{2}.

$$\frac{499}{2}+\frac{1000}{2}$$

Since \frac{499}{2} and \frac{1000}{2} have the same denominator, add them by adding their numerators.

$$\frac{499+1000}{2}$$

Add 499 and 1000 to get 1499.

$$\frac{1499}{2}$$

Factor

$$\frac{1499}{2} = 749\frac{1}{2} = 749.5$$
