Chapter 7.2, Problem 49STP

To determine

To calculate:To find that which one of them is not equivalent to $0.04\%$ .

Answer to Problem 49STP

Hence, optionJ is the correct answer.

Explanation of Solution

Given information:

F $0.0004$

G $\frac{4}{10000}$

H $\frac{1}{2500}$

J $4.0$

Calculation:

As per given information,

Convert the given inputs into percent multiplying by $100$

  $\begin{array}{l}0.0004=0.0004\times 100\\ =0.04\%\\ \frac{4}{10000}=0.0004\\ =0.0004\times 100\\ =0.04\%\\ \frac{1}{2500}=0.0004\\ =0.0004\times 100\\ =0.04\%\\ 4.0=4.0\times 100\\ =400\%\\ \end{array}$

Now, after converting each result, compare to $0.04\%$

We get,

  $400\%\ne 0.04\%,$

Therefore, option J is the correct answer
