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]
