Answer 1

9/20 as a percent- 45%

320% as a fraction- 16/5

2 3/8 as a decimal- 2.38

2 3/8 as a percent- 237.5%

.1% as a decimal- 0.001

.1% as a fraction- 1/100

1.2 as a percent- 120%

1.2 as a fraction- 6/5

5 1/3 as a percent- 533.3%

5 1/3 as a decimal- 5.33

Answer 2

1) 45%

2)
`(16)/(5)`

3) 2.335

237.5%

4) 0.0001

`(1)/(1000)`

5) 120%

`(6)/(5)`

6) 533.3%

5.333

Explanation:

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

`(9)/(20)=0.45*100=45\%`

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

`(320)/(100)=(32)/(10)=(16)/(5)`

3) As a decimal:

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

`2+0.375=2.375`

As a percent:

Multiply the decimal number obtained above by 100:

`2.375*100=237.5\%`

4) As a decimal:

Divide it by 100:

`(0.1)/(100)=0.0001`

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:

`(1)/(1000)`

5) As a percent:

Multiply 1.2 by 100, then:

`1.2*100=120\%`

As a fraction:

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

`(12)/(10)`

Reduce it:

`(6)/(5)`

6) As a decimal:

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

`5+0.33=5.333`

Multiply the decimal number obtained above by 100:

`5.33*100=533.3\%`
