Question

How do you express $ 2.39 $ as a percent?

Answer 1

Hint: In order to express a decimal number into its equivalent percent value we have to multiply the given decimal number with the 10 raised to the power 2 and add % symbol in the end to obtain your required result.

Complete step-by-step solution:
We are given a decimal number $ 2.39 $ .
In order to express a decimal number into its equivalent percent value we have to multiply the given decimal number with the 10 raised to the power 2 and add % symbol in the end
Now multiplying $ 2.39 $ with the number $ 100 $ and placing % symbol in the end, we get
 $
   = 2.39 \times 100 \\
   = 239\% \\
  $
Therefore, the conversion of decimal number $ 2.39 $ into percent is equal to $ 239\% $

Note:
1. Don’t forget to place the $ \% $ symbol after the multiplication .
2. To calculate fraction from the percentage , divide the given percentage value by 100
For example : We have to write $ 70\% $ into fraction
 $
   = \dfrac{{70}}{{100}} \\
   = \dfrac{7}{{10}} \\
  $
Or
 $ = 0.7 $
3. If you want to Increase a Number by y %:
Example:
-On the off chance that a number is expanded by\[10{\text{ }}\% \], at that point it becomes 1.1 times of itself.
-On the off chance that a number is expanded by 30 %, at that point it becomes 1.3 times of itself.
4. If you want to Decrease a Number by y %:
Example:
-On the off chance that a number is diminished by 10 %, at that point it becomes 0.90 times of itself.
-On the off chance that a number is diminished by 30 %, at that point it becomes 0.70 times of itself.
