Schritte zur Lösung

1 - (1 - 5%) (1 - 6%)

(1 - 5%) (1 - 6%) = \frac{19}{20} \cdot \frac{47}{50}

(1 - 5%) (1 - 6%)

1 - 5% = \frac{19}{20}

1 - 5%

= 1 - 5% \cdot 1

5% \cdot 1 = \frac{1}{20}

5% \cdot 1

Convert

5%

into a fraction:

\frac{5}{100}

5%

Rewrite

5%

as

\frac{5}{100}

= \frac{5}{100}

= \frac{5}{100} \cdot 1

\frac{5}{100} \cdot 1 = \frac{1}{20}

\frac{5}{100} \cdot 1

Multipliziere die Zahlen:

\frac{5}{100} \cdot 1 = \frac{5}{100}

= \frac{5}{100}

Cancel the numbers:

\frac{5}{100} = \frac{1}{20}

= \frac{1}{20}

= \frac{1}{20}

= 1 - \frac{1}{20}

1 - \frac{1}{20} = \frac{19}{20}

1 - \frac{1}{20}

\frac{20}{20} - \frac{1}{20}

Wende Bruchregel an:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{20 - 1}{20}

Subtrahiere die Zahlen:

20 - 1 = 19

= \frac{19}{20}

= \frac{19}{20}

= \frac{19}{20}

= \frac{19}{20} (1 - 6%)

= \frac{19}{20} (1 - 6% \cdot 1)

6% \cdot 1 = \frac{3}{50}

6% \cdot 1

Convert

6%

into a fraction:

\frac{6}{100}

6%

Rewrite

6%

as

\frac{6}{100}

= \frac{6}{100}
