Question

What is 280 decreased by 47.2 %? Round your answer to two decimal places if needed.

Answer 1

Given:

The original number given is 280.

Required:

The number is to be obtained by decreasing the original number by 47.2 %.

Explanation:

47.2% of the original number is calculated as,

$\begin{gathered} 47.2\text{ \% of 280 = }\frac{47.2}{100}\times280 \\ 47.2\text{ \% of 280 = }\frac{47.2\times280}{100} \\ 47.2\text{ \% of 280 = 132.16} \end{gathered}$

The new number obtained is calculated as,

$\begin{gathered} New\text{ number = 280 - 132.16} \\ New\text{ number = 147.84} \end{gathered}$

Answer:

Thus the number obtained by decreasing 280 by 47.2% is 147.84.
