Answer:

1) 45%

2) [tex]\frac{16}{5}[/tex]

3) 2.335

   237.5%

4) 0.0001

   [tex]\frac{1}{1000}[/tex]

5) 120%

 [tex]\frac{6}{5}[/tex]

6) 533.3%

    5.333        

Step-by-step explanation:

1) Divide the numerator by the denominator and multiply by 100, then:

[tex]\frac{9}{20}=0.45*100=45\%[/tex]

2) Write 320 has the numerator and 100 has the denominator, then reduce the fraction:

[tex]\frac{320}{100}=\frac{32}{10}=\frac{16}{5}[/tex]

3) As a decimal:

Divide the numerator by the denominator and add it to the integer part:

[tex]2+0.375=2.375[/tex]

As a percent:

Multiply the decimal number obtained above by 100:

[tex]2.375*100=237.5\%[/tex]

4) As a decimal:

Divide it by 100:

[tex]\frac{0.1}{100}=0.0001[/tex]

As a fraction:

As you can see, the decimal point were moved three spaces to the left. Therefore, the integer 1 is divided by 1000. Write 1 as the numerator and 1000 has the denominator:

[tex]\frac{1}{1000}[/tex]

5) As a percent:

Multiply 1.2 by 100, then:

[tex]1.2*100=120\%[/tex]

As a fraction:

To make 1.2 an integer you must multiply by 10, therefore, 12 will be the numerator and 10 the denominator:

[tex]\frac{12}{10}[/tex]

Reduce it:

[tex]\frac{6}{5}[/tex]

6) As a decimal:

Divide the numerator by the denominator and add it to the integer part:

[tex]5+0.33=5.333[/tex]

Multiply the decimal number obtained above by 100:

[tex]5.33*100=533.3\%[/tex]
