Respuesta :

1) 4.13

2) 0.1305

Explanation:

1) 413%

First we convert to fraction, then to decimal

[tex]\begin{gathered} 413\text{ \% = }\frac{413}{100}\text{ (fraction)} \\ \frac{413}{100}\text{ = 4.13 (decimal)} \end{gathered}[/tex]

3 is the hundredth place value.We do not have any number after it so we can't round up or down. It will remain the same

To the nearest hundredth, 413% is 4.13

2) 13.05%

It is already in decimal. Due to the percent attached to it, we will divide 13.05 by 100

[tex]\begin{gathered} 13.05\text{ \% = }\frac{13.05}{100} \\ =\text{ 0.1305} \end{gathered}[/tex]

5 is the ten thousandth place value. Since there is no value after:

0.1305 to the nearest ten thousandth is 0.1305
