Solve 54quad540(100-20/100)(100-5/100)

$$54 \quad 540 ( \frac { 100 - 20 } { 100 } ) ( \frac { 100 - 5 } { 100 } )$$

Evaluate

$$\frac{110808}{5}=22161.6$$

Solution Steps

Multiply 54 and 540 to get 29160.

$$29160\times \frac{100-20}{100}\times \frac{100-5}{100}$$

Subtract 20 from 100 to get 80.

$$29160\times \frac{80}{100}\times \frac{100-5}{100}$$

Reduce the fraction \frac{80}{100} to lowest terms by extracting and canceling out 20.

$$29160\times \frac{4}{5}\times \frac{100-5}{100}$$

Express 29160\times \frac{4}{5} as a single fraction.

$$\frac{29160\times 4}{5}\times \frac{100-5}{100}$$

Multiply 29160 and 4 to get 116640.

$$\frac{116640}{5}\times \frac{100-5}{100}$$

Divide 116640 by 5 to get 23328.

$$23328\times \frac{100-5}{100}$$

Subtract 5 from 100 to get 95.

$$23328\times \frac{95}{100}$$

Reduce the fraction \frac{95}{100} to lowest terms by extracting and canceling out 5.

$$23328\times \frac{19}{20}$$

Express 23328\times \frac{19}{20} as a single fraction.

$$\frac{23328\times 19}{20}$$

Multiply 23328 and 19 to get 443232.

$$\frac{443232}{20}$$

Reduce the fraction \frac{443232}{20} to lowest terms by extracting and canceling out 4.

$$\frac{110808}{5}$$

Factor

$$\frac{2 ^ {3} \cdot 3 ^ {6} \cdot 19}{5} = 22161\frac{3}{5} = 22161.6$$
