Question

1 Convert 413% to a decimal rounded to nearest one hundredth 2, Convert 13.05% into a decimal rounded to the nearest ten thousandth3. An ambulance needs to reach an accident scene in 10 min. At what rate of speed must the ambulance travel if the accident is 12 kilometres away ?

Answer 1

1) 4.13

2) 0.1305

Step-by-step explanation:

1) 413%

First we convert to fraction, then to decimal

`\begin{gathered} 413\text{ \% = }(413)/(100)\text{ (fraction)} \\ (413)/(100)\text{ = 4.13 (decimal)} \end{gathered}`

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

`\begin{gathered} 13.05\text{ \% = }(13.05)/(100) \\ =\text{ 0.1305} \end{gathered}`

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

0.1305 to the nearest ten thousandth is 0.1305
