Respuesta :

A. Let's convert the following percents into a fraction or a mixed number in the simplest form.

1.) 24%

4.) 150%

To be able to convert percentage into a fraction, we just apply the following formula:

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex]

We get,

1.) 24%

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex][tex]\text{ = }\frac{24}{100}[/tex][tex]\text{ = }\frac{\frac{24}{4}}{\frac{100}{4}}\text{ = }\frac{6}{25}[/tex]

Therefore, the fractional form of 24% is 6/25.

4.) 150%

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex][tex]\text{ = }\frac{150}{100}[/tex][tex]\text{ = 1 }\frac{50}{100}\text{ = 1}\frac{1}{2}[/tex]

Therefore, the fractional form of 150% is 1 1/2.

B. Express each percent as a decimal.

9.) 8%

14.) 568%

To be able to convert a percentage to a decimal, we just divide all percentages by 100.

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex]

9.) 8%

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex][tex]\text{ = 8 }\div\text{ 100}[/tex][tex]\text{ Decimal Equivalent = 0.08}[/tex]

14.) 568%

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex][tex]\text{ = 568 }\div\text{ 100}[/tex][tex]\text{ Decimal Equivalent = 5.68}[/tex]

Therefore, the decimal equivalent of 568% is 5.68.
