Solve {l}{100*50-10}{div20}

$$\left. \begin{array} { l } { 100 \times 50 - 10 } \\ { \div 20 } \end{array} \right.$$

Evaluate

$$\frac{9999}{2}=4999.5$$

Solution Steps

Multiply 100 and 50 to get 5000.

$$5000-\frac{10}{20}$$

Reduce the fraction \frac{10}{20} to lowest terms by extracting and canceling out 10.

$$5000-\frac{1}{2}$$

Convert 5000 to fraction \frac{10000}{2}.

$$\frac{10000}{2}-\frac{1}{2}$$

Since \frac{10000}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{10000-1}{2}$$

Subtract 1 from 10000 to get 9999.

$$\frac{9999}{2}$$

Factor

$$\frac{3 ^ {2} \cdot 11 \cdot 101}{2} = 4999\frac{1}{2} = 4999.5$$
